Arrrgh.
 
OK.  Maybe scrap that part of the patch then?

Its too bad they don't have a specific type of exception for this,
nor do they have a way to hold onto file descriptors under a type
like a SoftReference where the runtime can whack them if you have
too many.

I guess that's why Hadoop HBase just tells you to up your fd ulimit
to 32767.  :-)
