[webkit-dev] JavaScriptCore slowdown

[Rodney Dowdall]

Hello

I tracked down this problem to a stall in our ports rendering code when 
it tries to send a message to our main app.  Fixing the stall results in 
a bubblemark score of 243, which is on par with the other browsers I 
have on my system.  Thanks for all of the suggestions.

Regards,
Rodney
