Interrupting an infloop. Printing out a progress report.
Nope. To interrupt an infloop, you should be measuring process virtual
time (SIGVTALRM) , not realtime. Interrupting a deadlock, perhaps.
I also can't think of any progress reports that I want at running-time
intervals rather than realtime intervals!
It occurs to me that with a bit of luck, the problem will not be an
issue, because the auto-save timer fires every three minutes, which
should cause other timers to be expired, and that's often enough for
my purposes. (I was worried that my VM alarm facility would tell me 9
hours later about something I had to do that morning!)
