— Exceptions are now autoreleased.
This is safe as an "exception loop" can't happen, since if allocating
an exception fails, it throws an OFAllocFailedException which is
preallocated and can always be thrown.So, the worst case would be that an autorelease of an exception fails,
triggering an OFOutOfMemoryException for which there is no memory,
resulting in an OFAllocFailedException to be thrown. (user: js, size: 15789) [annotate] [blame] [check-ins using]

— Don't use madvise().
It turns out the overhead of calling madvise() is bigger than the gain
of using it. (user: js, size: 15227) [annotate] [blame] [check-ins using]
