[webkit-dev] WTF::fastMalloc

[Brent Fulgham]

So are you proposing to use the system allocator on Windows? Or would we keep using the existing FastMalloc implementation?

The current malloc logic has been the source of a number of mysterious crashes on Windows, so reverting to the system allocator might be a good thing for stability. I don’t know what the potential performance ramifications would be.
