Bug 141307 – [iOS] Remove False Positive dispatch_source Leak in WebMemoryPressureHandler singleton

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Joseph Pecoraro]

* SUMMARY
Remove False Positive OS_dispatch_source Leak in WebMemoryPressureHandler singleton.

I think we actually want to always keep this dispatch_source around. So we should just add a reference to it in WebMemoryPressureHandler.

* LEAK OUTPUT
Leak: 0x1657a1f0  size=112  zone: DefaultMallocZone_0x197e000   OS_dispatch_source  ObjC  libdispatch.dylib
