i propose that
the locking fopen function in the MH library be adapted to be willing to
try the advisory lock three times at one second intervals, on the
assumption that no writer will hold the lock that long and if there's a
convoy then we've got bigger problems. (ideally we'd do a wait-lock in a
thread and kill that thread if it waits too long, but threads would not
be "the MH way".)
I guess I was thinking in my head of the lock completely blocking, but
you think that having a timeout makes more sense? I'm neutral on that.
There's not a portable way of having a lock timeout other than loop/sleep,
is there?
