 Windows 7 64 bit, Cog Dec 12, 2012
bottleneck in method
CurrentReadOnlySourceFiles>>defaultAction
slow part is accessing changes file:
time to run: [SourceFiles second readOnlyCopy]  is ~ 100 ms. Caching
is introduced here some time after 4.1. On XP 32 bit without antivirus
there is no issue.. aha, perhaps this is antivirus related. Quite
common in corporate policy in environments today. Will try tomorrow to
disable antivirus and report.
