I would say that this is strong evidence that the newish implementation
of the CENTER keyword does something odd with memory: writing beyond its
bounds, leaking memory, etc. I would file this with ITT VIS support.

and if I take out the /center keyword to FFT, it goes away. A
miracle! What?

OK, so this is the statement that's causing the problem. After my
program executes this statement, everything I do causes the "checked
out" warning.
kern = shift(abs(fft(f2/(f1>1.e-10),/inverse,/center)),5,5)
IDL> print, 1
1
% Temporary variables are still checked out - cleaning up...
Any suggestions??

Oh, well, that's just shoddy quality control! ;-)

I take my criticism back... for some reason I'm getting the warning
from EVERY statement on the command line:
IDL> f1a = shift(abs(fft(psf1)),5,5)
% Temporary variables are still checked out - cleaning up...
What??

I'm sympathetic. My own graphics routines are tens of orders
of magnitude simpler than the NG functions, and yet I groan
inwardly whenever I hear about a new problem. When things
get this complex, "fixing" a problem is only the start of
your woes.
