gdb_assert() generates an internal error if the condition in question
does NOT hold.  So for the above, an internal error will be generated
if !(signo == TARGET_SIGNAL_0).

Please note the exact context of this assertion.  I.e, we have a
wait status already associated with the thread.  You should also
read the FIXME just prior to the assert.

Yes.  (Well, technically, it causes all LWPs to resume.)
