MPI profiling for hanging code

[aruhela]

mpiP generates the profile if a program ends completely. Is it possible to generate the profile after some time as many codes either never completes (generate intermediate files) or have some programming issues. This would be helpful to debug the slow/hung applications to identify what communication operations were used and in what message range. A simple environment variable might be implemented to trigger the writing of the mpiP report at some specified time.
