The current versions of gawk have two environment variables that
affect this.  From the development gawk man page:

For socket communication, two special environment variables
can be used to control the number of retries
.RB ( GAWK_SOCK_RETRIES ),
and the interval between retries
.RB ( GAWK_MSEC_SLEEP ).
The interval is in milliseconds. On systems that do not support
.IR usleep (3),
the value is rounded up to an integral number of seconds.

The code is in io.c; look for getenv.  These are probably not documented
in 3.1.8.

HTH,

Arnold
