I am getting several displays from Aspen (errors)

Moving this from CCSI-Toolset/FOQUS#45:

I am not sure if this is a SimSinter issue, but lets see. I am getting several errors from aspen (see attached figure).

The figure has 10-20, but I left the computer running all the night and this morning I had to close about 100-150.

Reproducing @boverhof comment from old issue:

Think this is happening because "open Aspen Engine" hangs and never returns in SimSinter. Possibly because the simulation and inputs are just not reasonable...

Since the forking process in SimSinter never discovers the PID of the child process it's dicey killing the process. But this scenario is unacceptable and at the least SimSinter shouldn't open more if there are already Aspen processes sitting around.
