Temporarilly disable SetURL to evaluate perf impact
Temporarilly disable SetURL to evaluate perf impact

This is a temporary checkin, meant to gather data from the bots that run 
performance tests.  I'll revert it asap.

Profiling suggests we call SetURL VERY often, so that we can get crash
info.  The function turns out to cause a memory allocation, and also a
string conversion, and hence *might* have a significant perf impact.
