[Research] "Too many open files" error

[Michael J. Baysek]

It looks like there were bugs introduced into dsut.c back in July that 
caused this problem.  The bug was triggered if you were loading lots and 
lots of datsets within your program.

Anyway, we figured it out.  Purna is committing the fix.  Everyone 
should update your dset directory.
