Thanks for the report.

I've fixed this problem in the latest source (exp-tagged in CVS), at
least for the crash I see in Win98.

I don't understand exactly why the crash happens. DrScheme crashes
*after* it calls _exit(), which is supposed to terminate the program
without doing anything else. MzScheme also calls _exit().

I worked around the problem by removing the call to _exit() in most
cases; it's usually not necessary. Using `subprocess', `system', etc.,
will trigger the call to _exit(), though.
