Thanks for you answer Diogo, it actually made me think that I could use
`sync/timeout' instead of trying to poll directly:
(sync/timeout 0 (scheme_fd_to_semaphore s MZFD_CREATE_READ #t))

Unfortunately this does not work :)
It always returns #f.
I tried with MZFD_CHECK_READ instead, but got a segfault.

Probably I should wait for the documentation of `scheme_fd_to_semaphore'
