 Hello,
 
 At present GDB maintains a thread-db that contains all the "threads" 
 known to GDB.  The list is cross-target.  That is, it can include both 
 LWPs from the lower "process layer" and "threads" from the higher 
 "thread layer".
 
 I think the currently implicit target <-> thread relationship should be 
 made more explicit:
 
 - thread_info should point back at it's target
 - a target should let you iterate over its "threads"
 
 This, I belive, will help clean-up the current tid:pid dance.  A thread 
 would always know its target and hence thread operations would always be 
 applied at the correct level.
 
 thoughts?
 Andrew
