Just to follow up for the web archives, this is *likely* connected to
the critical bug that we recently announced:

We're having problems with code that uses BLACS and openmpi 1.3.x.
When compiled with memory-manager turned on (base only), code using
BLACS either start leaking memory or gets into some kind of deadlock.
The first code-case can be circumvented by using
mpi_leave_pinned_pipeline 0, but the second one could only be solved
by
compiling openmpi without memory manager.
Building 1.3.1 with ptmalloc2-internal makes the second code break in
different ways.
Anyone else seen similar problems when using BLACS?
