Yes, that's true. So what? How should one debug a program that uses a
simple delay? A program that behaves funny under the debugger
behaves funny. Recall that I answered the original question by
saying "the behavior may be surprising." I stand by that statement.:-)

Actually, I've been messing with GDB on Solaris to see if there's a
workaround. It turns out that SIGWAITING is raised, apparently, 
whenever a delay or whatever is encountered in the program. On
Solaris at least, typing, at the gdb command prompt,

handle SIGWAITING nostop
handle SIGWAITING noprint

seems to work. I haven't tried this (yet) on other platforms.

In any event, this is not the least bit obvious to a non-GDB expert.
