Hmm...  OK; thanks.  I went ahead and grabbed crash dump; it may be
found at <> (along
with core.txt).

Also, my laptop (running a kernel based on GENERIC, but with a few bits
snipped out and things like IPFIREWALL_DEFAULT_TO_ACCEPT turned off) did
not exhibit an issue.

I am presently re-building head _at_r331290 on each machine (on a different
slice); this time, without the Forth loader stuff being built (and with
the Lua loader stuff being built).  I mention this, not because I think
the loader has anything to do with this, but because at this time, I
have but a single failure out of two possible; smoke-testing the current
builds will provide a chance to see if I somehow did something weird to
the build machine earlier.

Anyway, Warner should know how to reach me. :-)

The fix is in 331291.. at least the back out for other issues...
