Avoid updating hidden page timer throttling interval for suspended processes
https://bugs.webkit.org/show_bug.cgi?id=270236
rdar://problem/123773191
Reviewed by Chris Dumez.
Currently, every time a tab is created or destroyed, we update the hidden page
timer throttling
interval and broadcast the change to all processes, including suspended
processes. While this
doesn't cause a suspended process to resume, it can cause messages to build up
in IPC queues that
never get drained. This is because the receiver might be a suspended WebContent
process.
To avoid this, skip sending the timer throttling interval to suspended
processes and defer the
update until the resume IPC.
