First, okay, I blew it on the wildcard issue, as about 20 people were
kind to say by direct mail.  Oh well, thats what I get by using NewS
for a mental break at 3 AM in the middle of a compiler construction
project. :-).

But, now a real question.  I have a mediumish heavily intuitionalized
program.  There are menus, two scrolling list type boxes, and several
gadgets.  Memory usage is about 170K out of 3-4M free.  I dont have
any memory leaks (squashed the last one last night).  I am running the
release 2.02 on an early 3000.

The problem is this.  If I do something to generate IntuiMsgs *very*
quickly (like type very fast, etc) and Process the messages quickly
(ie: Get/Reply) them, when I exit memory is *severly* fragmented (ie:
Largest block <50K. If I do it again, largest block <10K).  If I 
comment out all message handling code, so that I am ONLY Get/CHeck for
CLOSEWINDOW/Reply the problem still occurs.  If I let the messages
queue up w/o processing, then exit, no problem.  If I process slowly,
but type quickly, still problem.

The problem seems independant of which actions I do, only that they
happen quickly.

After exiting if I run AVAIL or any big command, I get a recoverable
Guru 0100000C (AVAIL problem or some such), which turns
non-recoverable inside a program.

Any suggestions?  (I'm not sharing the IDCMP port, I'm not falling
behind in Msgs, etc).  Oh, one side note, all my Amiga allocations are
VIA Alloc/FreeRemember().  I added some tracking code and I am freeing
all Remember Keys, and not freeing any Invalid ones, and I am using
TRUE for the flag.

One other note.  The slower the machine, the more likely the problem
is to occur and the last fast something needs to be (on a 3000 I can
cause it about 1 out of 4 times, on a vanilla 2000 I can cause it 9
out of 10).

Lessee, we've got IDCMP Flags of CLOSEWINDOW, GADGETUP/DOWN, MENUPICK,
ACTIVATE, VANILLAKEY, INTUITICKS, NEWSIZE, REFRESHWINDOW.  The window
is SIMPLE_REFRESH.  There's never any XXXVERIFY msgs, and gadgets are
of all varieties.
