This has happened randomly forsome time while running the webkit
testsuite. Now it happens reliably.
Symptoms: screen just stops drawing. Attaching to the machine by ssh I
noticed app_server is not running anymore. And I see this in the syslog:
{{{
KERN: 100610: DEBUGGER: Could not create BWindow's receive port, used for
interacting with the app_server!
KERN: _user_debugger(): Failed to install debugger. Message is: `Could not

It would be nice to have some better user feedback in that case (panic or
a message to /dev/console). I will try to find why I seem to be running
out of ports.
