Reinstall signal handler

SysV semantics in Linux signal(2)
seems to imply SA_RESETHAND therefore
we should reinstate the signal
handler whenever it is called, as our
signal handlers are re-entrant.

We still have a problem when using
BSD signal(2) semantics (SA_RESTART)
imply restart the system calls if
not asked otherwise.
