Yeah, IIRC Win98 did the same thing. Basically VirtualBox doesn't
know when the hosted system is idle.

I'd do development under real-DOS (quick to reboot when it dies), or
under an emulator - Win98 is probably not the best choice as it's too
easy to kill it, and it takes a while to reboot.

There are many ways to move files to and from DOS machines, here are
some ideas, and notes on the DOS software I've successfully used:

FLOPPY: standard across platforms, good for up to 1.4MB, not supported
on most new hardware. You can use USB floppy drives under windows, and
some systems have mainboard FDC support even if no floppy drive(s) are
installed (so all you need is a drive and cable).
No special software required.

HARD DRIVE: Moving a hard drive between DOS and other machines can be
a very easy way to move large files - I use removable IDE carriers to
make it easy to move drives - you can also use a USB enclosure or drive
cable to interface the drive to more modern systems.
No special software required.

CD/DVD: Easiest way to get large files into DOS, but basically one-way
(no viable DOS CD writing software that I know of), and requires burning
disks. Needs CD/DVD driver and MSCDEX (or equivalent).

USB mass storage: Can be tricky to setup and use under DOS. There are
several drivers available - I've used the panasonic drivers: USBASPI.SYS
and DI1000DD.SYS with reasonable success.

Serial: Slowish, but works well for DOS-to-DOS transfers. Can work ok for
DOS-to-windows if you can find decent software. Lack of real serial ports
on modern hardware can pose a problem, especially when using older software.
Software I use:
  My own DDLINK
  Microsofts INTERLINK
  TTY program with X/Y/Zmodem etc. (not as easy as above)
  Networking software with serial packet driver (can be tricky).

Parallel: Works really well for DOS-to-DOS transfers, but virtually
impossible to make work under windows - and not supported on most newer
hardware.
Software I use:
  My own DDLINK
  Microsofts INTERLINK
  Networking software with LPT packet driver (can be tricky).

Ethernet: Standard across all platforms, and still supported by "everything".
Can be tricky to find DOS drivers for modern hardware, however older PCI and
ISA network cards are common and easy to install in most systems:
Software I use for DOS-to-DOS:
  My own DDLINK
  My own TFTP (tiny & does client and server)
  Neos (tiny DOS-to-DOS network I used to use, a little weird to set up,
        but I wrote a replacement setup program that made it easier).
Software I use for DOS-to-WINDOWS:
  Microsoft network client (I can give you details on how to distill the
       DOS client files from Windows for Workgroups if you wish).
  My own DDLINK     (use SWSVPKT virtual packet driver under windows)
  My own TFTP       (I use "pumpkin" as a windows TFTP server)
  Mike Brutmans FTP (I use "warftp" as a windows FTP server)
Software I use for DOS-to-OtherNonWindowsSystems:
  My own TFTP
  Mike Brutmans FTP
