Just move the call that tries the mmap of the pch file to the 
validation routine.  The issue there is we'd need to think about trying 
to mmap twice.  Currently, we only ever do it once.  We would try and 
mmap more than once when there are multiple PCH files for the same 
source, as we run thought all of them, trying to validate each one.

This issue is known and expected and not an issue.
