Summary:                    dead lock
Description: 
in channel.c 's function ast_read use lock in order of chan then spy, while
in app_chanspy.c's function channel_spy use lock in order of spy then chan.
these order seems easy to cause dead lock when lots of spies(more than 100
spies spy on more than 4 channels). BTW, when i add spies more than 104,
some of my clients begin hangup by asterisk. i am confused by this.
