[asterisk-dev] What happened with the DEBUG_THREAD define in the asterisk Makefile?

[Juan Carlos Castro y Castro]

There's no mention of it in the current SVN version. Version 1.2.7.1 had 
the following:

# Optional debugging parameters
DEBUG_THREADS = #-DDUMP_SCHEDULER #-DDEBUG_SCHEDULER #-DDEBUG_THREADS 
#-DDO_CRASH #-DDETECT_DEADLOCKS

Also, the "howto debug a deadlock" at 
http://www.voip-info.org/wiki/view/Asterisk+debugging seems to be out of 
date -- it doesn't tell what DUMP_SCHEDULER, DEBUG_SCHEDULER and 
DETECT_DEADLOCKS are for, how can they be used, or what caveats are 
associated with enabling them.
