>Description:
When typing quickly at the console, TME sometimes asserts:

tmesh> assertion "!pressed_old != !is_press" failed: file "keyboard.c", line 
1688, function "_tme_keymode_stage"
[1]   Abort trap (core dumped) tmesh s2


pressed_old and is_press were both 1.


I am not able to reproduce the problem on command.  Rarely when typing fast the 
above occurs.  More often when typing fast, the shift key hangs a while 
(without an assertion), so that entering:

rm *.tmp
becomes
rm *>tmp

which is a little annoying.  :)
>How-To-Repeat:

>Fix:
I commented out the assertion via the following patch, so that I could continue 
running the emulator and see if any other assertions popped up.

TME seems to run fine with the following commented out (or when TME is built 
with --disable-debug) but the problem should be investigated before electing to 
permanently remove the assertion.
