I start emacs with option -Q and the buffer listing shows:
. * *gud-umc.vx* 1140 Debugger:run
*scratch* 0 Lisp Interaction
* *Messages* 199 Fundamental
* *partial-output-umc.v: 31 Fundamental
%* *breakpoints of umc.v: 31 Breakpoints

When I start gdb in emacs, 'top' shows that gdb is running at about 50% CPU
for more than a minute and then the load goes slowly down to a value below 1%.
This takes about 2 minutes. Another thing that is a bit odd is, that the gdb
prompt in emacs appears after about 15 seconds, which makes the user think
that emacs/gdb is ready. But when I enter e.g. 'h RET', I have to wait for
nearly 2 minutes till the help output is printed.
