Reviewed by Alex Christensen.
Parallel calls to [WKContentRuleListStore compileContentRuleListForIdentifier:]
for
the same identifier can fail. This is because we process the requests on a
concurrent
work queue and different threads may thus end up interacting with the same file.
Address the issue by using a static serial work queue for filesystem operations.
This might fix <rdar://156150166> though it is hard to confirm this is the root
cause.
