Ok, here it is:

NOTE 1: process 517: this process seems to be the most active. Multiple
        breaks after continuing result in different traces.
NOTE 2: process 518: there's no linux_poll in the source tree. This is a
        local change.
NOTE 3: process 520: syscall 0 is an invalid Linux syscall (used to be
NOTE 4: this is not reproducable on Alpha, because it panics even before
        loading mozilla, but this is for later.

I'll go with my hunch (sp?) that it's linux_clone and see if I can find
the evidence. The systems looks responsive, but everything that relates
to processes (creation, destruction) seem to queue up. At least that's
how it "feels"...
