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.)
