What OS are you using? Is is a BSD OS? If so, you may be right about
item 34. I appear to have fallen in a pit into which I keep repeatedly
falling, by writing signal() instead of os_non_restarting_signal(). This
works on Solaris and Linux, so I never notice. (Why, oh, why, are the
defaults different?)
You can test out this hypothesis by changing line 275 of exim.c from
void (*oldsignal)(int) = signal(SIGALRM, sigalrm_handler);
to
os_non_restarting_signal(SIGALRM, sigalrm_handler);
and changing line 201, which reads
signal(SIGALRM, oldsignal);
to
signal(SIGALRM, SIGIGN);
This is a hack, but I think it will work. (It now doesn't preserve the
signal setting, it just disables it, but I think that was just
tidiness.)
