pgalloc: Do not hold MemoryFile.mu while calling mincore.
...
This change makes the following changes:
- Unlocks MemoryFile.mu while calling mincore (checkCommitted) because mincore
can take a really long time. Accordingly looks up the segment in the tree
tree again and handles changes to the segment.
- MemoryFile.UpdateUsage() can now only be called at frequency at most 100Hz.
100 Hz = linux.CLOCKS_PER_SEC.
