Several comments:

1) I'm not a POSIX/Linux developer either.

2) Since fork is non-standard and not part of Boost.Threads, you're
technically in undefined territory as far as Boost.Threads is concerned.

3) Since Boost.Threads should play nice here, despite what I just said in
(2), if there is a problem (see 1) it should be fixed.  If anyone  can
shed light on this (and maybe even a patch), it would be appreciated. 
Other wise, I'll add this to my todo list, though it will be scored low.
