   why do we need to make it uninterruptible?
   
   Is there a risk of problems if one thread is waiting for the semaphore and 
the process is exited?

> {{FileSystem}} "creator permits" are acquired in an interruptable way.  This 
> changed the behavior of the call because previous callers were handling the 
> IOException as a critical error.  An interrupt was handled in the typical 
> {{InterruptedException}} way.  Lastly, there was no documentation of this new 
> event so again, callers are not prepared.
> Restore the previous behavior and lock the semaphore Uninterruptibly.
