Hi,
Following the other email on new regex performance here is a patch that
remove the memory available check on Win32 (i.e. XP, Vista, etc.) It's
accuracy was questionable on Win32 (numbers returned will most likely be
out of date by the time it is used), the system will be on its knees by
the time there is just 8KB left, and so on. It provides a performance
boost in memory allocation intensive operations (e.g. new regex engine)

This is certainly more fun than being hit with a hammer.
