4.2 signal handling

[VLD/VMB]

Yes, on 4.2BSD interrupted system calls are restarted when the user
interrupt handler returns.  There is no simple way to obtain the
previous UNIX behavior (EINTR error return from interrupted "slow"
system calls).  I once posted an emulation of signal(2) for 4.2BSD;
it was VAX-specific but the kludgery used could be adapted to other
architectures.  If you are interested in this routine, send me mail.
