• Fixed IndexFS.rename and IndexFS.renameSync not behaving correctly.
  • Items are now correctly removed bottom up and re-created top down
• Fixed mkdir in derived file systems not being compatible with Async(IndexFS)
  • Added internal IndexFS._mkdir and _mkdirSync, which are called by IndexFS when creating new directories and renaming existing ones
• Added timeout argument to _MutexedFS.lock()
• --test-force-exit is no longer used when testing, which means more bugs should be caught
