Fix a major bug in autoservice.  There was a race condition in the
handling of
the list of channels in autoservice.  The problem was that it was possible
for
a channel to get removed from autoservice and destroyed, while the
autoservice
was still messing with the channel.  This led to memory corruption, and
caused
crashes.  This explains multiple backtraces I have seen that have
references
to autoservice, but do to the nature of the issue (memory corruption),
could
cause crashes in a number of areas.
