We had this discussion before: sometimes, DJGPP programs run slowly in 
Windows DOS box.  I originally thought this was because v2.01 didn't align 
the stack.  However, I now am convinced that v2.02 didn't solve this 
problem.  (I did verify that the stack has its 4 low bits zeroed.)

The funny thing is, some DOS boxes run the same program faster than 
others (about 2-4 times faster, to be exact).  Closing the DOS session 
and reopening it doesn't help.  Rebooting helps, but it only changes 
which DOS boxes run fast and which slow (I need at least Emacs to be 
fast).

What could be the reason for this?  Is something else (code? data?) 
unaligned?  What would be the easiest way to check for these problems?
