Very interesting!
However... this library is a core package, and maintained by
libraries@..., so you should not release it yourself.
Instead, submit your patches to libraries@ for inclusion, following the
patch submission guide here:
http://haskell.org/haskellwiki/How_to_write_a_Haskell_program
Where the patches will be tested on other unix platforms, and then
encorporated into the main 'unix' repository.
Also, as unix .hsc files tend to be a bit fragile, portability wise, it
might be a good idea to instead place your patches in a separate library
on hackage, rather than patching the 'unix' package directly. We have
many other unix-alike packages, so one for message queues, and real time
scheduling make sense -- separate from the core 'unix' package (like the
mmap package, for example).
