For the paranoid (and I count myself among them) you can DetachResource to make
a private copy of the cursor for yourself.  This avoids having to have copies
in your resource file.

In general, I am not sure what one is supposed to do about shared system
resources.  I don't want them cluttering the heap if I no longer need them, but
I don't want to offend DAs.  Perhaps one should GetResource before EVERY use
of the resource, but mark it purgeable... but then you have to decide what to
do if there is not enough room in the heap to reload it.

At least Cursors are small.
