Description Martin Roskanin 2004-05-24 10:05:25 UTC 
During typing in editor the typing is sometimes
sluggish, this occur after some idle time (maybe
after background parser triggers) or after typing
"new " or "." when completion popup is triggered.
After measurements in OptimizeIt, 49% of AWT is
taken by JavaEditor$10.actionPerformed() ->
JavaEditor$JavaEditorComponent.selectElementsAtOffset()
that enters javacore.ExclusiveMutex.enter()

AWT is blocked by waiting for Mutex leave, what
can depend on CompletionQuery finishing or some
other background process that locks Mutex.

I moved several "beginTrans's" from awt thread. AWT is not blocked on
my windows machine any more. Please verify on different platform or
reopen if awt is still blocked during typing.
