Set task priority of WebKit2 processes to zero on Mac
https://bugs.webkit.org/show_bug.cgi?id=102567
Patch by Kiran Muppala <cmupp...@apple.com> on 2012-11-16
Reviewed by Mark Rowe.
Explicitly set task priority of WebKit2 processes to zero, to
override automatic priority determination by the system.
* Shared/ChildProcess.cpp:
(WebKit::ChildProcess::ChildProcess): Add call to platformInitialize() and
move MAC specific call to disableProcessSuppression to platformInitialize.
(WebKit::ChildProcess::platformInitialize): Dummy for non MAC platforms.
* Shared/ChildProcess.h:
* Shared/mac/ChildProcessMac.mm:
(WebKit::ChildProcess::platformInitialize): Add call to setpriority().
