I think that current being current might be the culprit.  I tried to
reproduce this & couldn't.

It crashed previously on a single-threaded make buildworld -- that
worked fine this time, as did a make -j4 buildworld.  A make -j32
buildworld died with an unrelated  'panic: vm_page_insert: already inserted'
 -- this was with a stack that came out of execve,
exec_copyout_strings, bcopy, bcopy_lp -> XentMM ... vm_fault...vm_page_alloc().
(all lost on a graphics console; I really wish ddb used a normal printf
so that I could get a damned stack trace back out of dmesg..)

Anyway, it looks like this is not reproducable.  I'm sorry I wasted
your time.
