Did you experience a freeze?

There is a simply test in the guest if it's not rate limit:

# time ls
anaconda-ks.cfg  Documents  install.log         Music     Public     Videos
Desktop          Downloads  install.log.syslog  Pictures  Templates

real    1m26.053s
user    0m0.311s
sys     0m1.813s

'ls' command cost about 1.5 minute, if we run the memory test program, i think
the time/delay is unacceptable...... :-(

Marcelo, would making the ratelimit optional help? personally I think without ratelimit audit is useless, and with ratelimit it is a lot less useful but can still point out problems. But I haven't used it in a while.

I have a truly marvellous patch that fixes the bug which this
