don't know if it happens to everybody, but when it happens to me i'm not sure 
if i should maybe kill the ide
Comment 2 Dirk Baeumer CLA 2003-02-11 14:04:43 EST 
Regarding the stack trace there are two thread active

main with org.eclipse.jdt.ui.ProblemsLabelDecorator.getErrorTicksFromMarkers(Pr
oblemsLabelDecorator.java:213)

and 

Decoration doing some CVS decorations.

Adam, can you please doa performance analysis to see if it is the problem 
decorator or the CVS decoration.
Comment 3 Dirk Baeumer CLA 2003-02-12 05:18:28 EST 
After looking at the stack trace again I come to the following conclusion:

Launching triggers a build that is executed in a model context thread. When the 
build is finish the build action calls done on the progress monitor which 
causes a sync exec. (see stack trace of Modal context thread).

Since the UI thread is busy executing label decorator runnables (the delta has 
already been send out by ending the build actions), the model context thread 
has to wait until all already existing decorator runnables in the queue has 
been executed.

This causes a situation where the user gets the feeling that the UI is froozen.

The problem seem to related to bug 30296.

Moving to platform.
Comment 4 Adam Kiezun CLA 2003-02-12 06:36:04 EST 
I got it again and the stack trace of the Main thread is below. So it is 
actually processing ruunables since every request of a thread dump shows a 
different main stack trace (tested 10).
