Actually, for SunOS-4.1:
If the process calling recv(), recvfrom() or recvmsg()
receives a signal before any data are available, the system
call is restarted unless the calling process explicitly set
the signal to interrupt these calls using sigvec() or sigac-
tion() (see the discussions of SV_INTERRUPT on sigvec(2),
and SA_INTERRUPT on sigaction(3V)).
