[Discuss] Making read() non-restartable

[Peter Scott]

I may be a bit out of my depth here, but I have at least (tried to) 
read Stevens on the subject.  It appears that read() is restartable by 
default.  I want it to not be restarted after SIGALRM.  How/can I do 
that?  It's getting restarted even though SA_RESTART was not specified 
in sigaction().  And SA_INTERRUPT is a no-op according to 
bits/sigaction.h.  (Yeah, I'm doing it in Perl, but I straced it so I 
could see the system calls and that's where I see read() returning 
ERESTARTSYS.)
