New Revision: 28872
ViewCVS: http://svn.berlios.de/viewcvs/haiku?rev=28872&view=rev

Modified:
   haiku/trunk/src/kits/tracker/PoseView.cpp
Log:
* The pose adding thread was going too fast, opening too many files (those are closed by the window thread), and 
reaching the file descriptor limit. For some still unknown reason, this was causing GetNextDirents to stop returning new 
entries. The result was that, on populated folders, Tracker wouldn't load all poses and stop at a random amount.
We now take a more conservative approach and close the files before sending, reopening them on reception.
 
Now the AddPoses thread is a bit too aggressive, especially on second runs, i needed to add some snoozing otherwise it 
would stall Tracker for several seconds. (testing on a 20000 files folder).
This fixes #3054
