Btw here it's ctrl-alt-2 to get to the monitor at least with sdl.

 No I cannot reproduce that (at least on 6.3/i386 and an older
7-stable/amd64), can you get a backtrace?  (do something like:
        gdb 
/usr/ports/emulators/qemu-devel/work/qemu-snapshot-2009-01-18_18/i386-softmmu/qemu
 qemu.core
and then in gdb do `bt' - that qemu executable below the work/ dir should
still have debug symbols so you'll get a more meaningful backtrace than
with the installed executable from below /usr/local/bin.)

 I do notice tho that the monitor output on vc is slow now, almost as if
coming over a 1200 bps serial line or so... :)  So definitely _something_
has changed.  (now that I look for it, the guest's vga textconsole might
have been faster before as well, tho its not _as_ slow as the monitor.)

 Oh and if I put the monitor on qemu's tty (-monitor stdio) its also
not slow.
