| Description |
|
A "remapLock" critical section was added to the Windows version to try to prevent MapViewOfFileEx failures, but we were unable to make the code bulletproof using this method and eventually solved it a different way. Performance tests show that this code cause a 3% loss of performance on some tests, so we should just remove this code to get this performance back. |
