{{{

I noticed that the tests with Hydra were hanging (and not timing out)
for the shared library case in the nightlies (on crunch and triumph). In
trying to reproduce the problem manually, I find the following:

* build with shared library: all tests hang

* build without shared library: all tests either hang or give this error

crunch:/sandbox/thakur/tmp/test/mpi/attr% mpiexec -n 2 attrend
Fatal error in MPI_Finalize: Other MPI error, error stack:

The exact command line is
/homes/thakur/cvs/mpich2/configure --enable-nemesis-dbg-localoddeven
--disable-spawn --with-device=ch3:nemesis --enable-sharedlibs=gvv
--with-pm=hydra --prefix=/sandbox/thakur/mpich2-install

On 64-bit systems everything runs peachy.
