New description:

 If I have two Cactus trees both using the same configuration names and the
 same simulation directory,  I believe that the executable cache in
 simulations/CACHE will suffer from collisions between the cached
 executables in the different Cactus trees.  A solution would be to use a
 unique name for the executable, just as is done when purging simulations
 to the TRASH directory.

 I am hesitant to set the ET_2013_05 milestone, but a fix which would make
 it into the release would be very welcome.

Comment:

 Bumping this up a little since this can be really a bad surprise, and be
 hidden from the user for a while. It also isn't all such an exotic setup.
 Using the same configuration name is easy - just use the default 'sim' in
 all Cactus trees.
