Commit e6788850078974de6fc5eaee70fe463d24d953db by sdolan
Lock channels before doing I/O

The debugger's use of channels doesn't support locking, but it
doesn't work on threaded programs anyway.

Commit 15b9d006a4792c88d0c461e8280d932364cb1404 by sdolan
Avoid polling in caml_leave_blocking_section

To preserve behaviour, explicit polls are added:

   - in caml_raise, to raise the right exception when as system
     call is interrupted by a signal.

   - in sigprocmask, to ensure that signals are handled as soon
     as they are unmasked.
