to cut down on BRegion related allocations, cannot really tell
if it speeds things up
* used the new BRegion pool in WindowLayer and ViewLayer whereever
a BRegion was used on the stack
* fixed the debugging stuff in MultiLocker - it will get you into
the debugger if you
- try to nest read locks
- try to write lock when your are a reader already
- don't match up nested locks when your a writer
-> but only if you #define DEBUG 1 in the .cpp, is off by default now
* went over WindowLayer, ServerWindow, Desktop and a few other places
and fixed the locking for use with the MultiLocker, the "a reader can
not become a writer" is especially tricky, feel free to review the
changes
* activated the MultiLocker, I tested this quite a bit, if there are
problems simply turn on DEBUG and you should drop into the debugger
right where the problem is... hope all is good
