Ok, thanks Xavier and Damien for the answers.

Let's go to the next level:

1) {enter,leave}_blocking_section are defined in byterun/signal.{h,c}
   and shipped inside libcamlruntime.a. The problem is that signal.h
   isn't shipped in the standard ocaml includes, I can obviously trick
   the C compiler, but is this the intended behaviour?

2) looking at otherlibs/unix/connect.c I see this block of code:

      enter_blocking_section();
      retcode = connect(Int_val(socket), &addr.s_gen, addr_len);
      leave_blocking_section();

   Int_val is used inside the blocking section. I guess that this is
   safe because integers aren't heap allocated. Tell me if I'm wrong.

Cheers.
