Function.prototype.toString triggers page demand on Speedometer
https://bugs.webkit.org/show_bug.cgi?id=225678
Reviewed by Mark Lam.
Some JS libraries -- e.g. jQuery, Ember-Debug, Angular -- like to
toString() JS functions in order to enforce return type, argument type,
or deprecation invariants. This triggers pathological page demand if
we keep throwing away the underlying script string.
* loader/cache/CachedResource.cpp:
(WebCore::deadDecodedDataDeletionIntervalForResourceType): Let's try 5s.
