[Egor Starkov]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4
Build Identifier: 

Browser stalls until any event happen in system. It happens because mayWait flag is TRUE in nsAppShell::ProcessNextNativeEvent and core goes to idle loop. Backtrace is in attachment.
mayWait flag is FALSE in nsThread::ProcessNextEvent but after it is lost and not handled, so it becomes TRUE. It happens because mayWait is not passed as parameter and default parameter is used.

Reproducible: Sometimes

Steps to Reproduce:
1. open browser
2. type 'g' in address bar
3. press enter
Actual Results:  
broser stalls sometimes and continues loading after some events like clicking

Expected Results:  
browser should load page immediately

Here is the GTK workaround  for this problem.
https://garage.maemo.org/svn/browser/mozilla/trunk/microb-engine/microb-engine/debian/patches/not_sorted/92422.workaround.diff
We are pushing event into queue if there are no any events and myWait = 1.
