it means that, should the parent do something like

   exec 'another_program.exe'

the pipe will be closed.  it's important since pids are recycled and pipes
transfered the slave would live on for while - perhaps indefinitely.

of course it's possible that behaviour is desireable, but then a zombie would
also be created... anyhow, for hacking it's safe to comment that out.

this could easily be configured - check out how the other stuff is configured
and do something like allow the ENV var 'SLAVE_DRB_PROTOCOL' to override
this...  perhaps a better option might be

   Drb.start_server 'drb://localhost.localdomain:0'

note that 'nil' here doesn't work on macs for some reason...

i'm running out the door now, but i'd love to make this work on windows - just
for the challenge.  maybe dan can lend a hand? ;-)

maybe we can work together and make another release that's portable.  ping me
offline if your're interested.

cheers.
