interesting!

ok, you could disable that by taking out the configure tests for
HAVE_SETRESUID and HAVE_SETEUID.

then again, put a sleep(60) in the smb_panic() function, i do this _all_
the time.

then again, if you are running X-windows, do this:

"panic action = DISPLAY=:0 xeyes"

:)

then, when the eyes appear, go do a gdb attach :)
