Or ksh-ism? (Or does it even matter which one it is originally, since 
Bash is GNU Bash with features common with ksh.)

Regardless, subsecond sleeping is useful and Bash already supports 
handling subsecond times in at least 'read -t', so it's not that far 
fetched to implement it in 'sleep' too.

I'd still suggest supporting the features in GNU coreutils sleep, if an 
enabled-by-default builtin sleep is implemented. Just for those systems 
that happen to have both GNU Bash and GNU coreutils installed.
