Hi Richard,

I have not experimented with this configuration yet myself, its always 
been all one way or the other.

Is one way or the other coming "close" to working right?  I would guess 
that if libc and mpich are dynamic, then the LD_PRELOAD method might at 
least capture posix and mpi-io calls, but would miss the HDF calls, for 
example.

thanks,
