Two things:

1. Doh; I suggested a poorly-named environment variable.  For reasons  
you don't care about, "OMPI_MCA_memory_ptmalloc2_disable" would be a  
better name for us (vs. "OMPI_MCA_disable_memory_allocator").  Sorry  
about that!  I just committed the check for  
"OMCA_MCA_memory_ptmalloc2_disable" upstream:

     https://svn.open-mpi.org/trac/ompi/changeset/21479

2. If you want a more general env variable name, like checking for the  
presence of $FAKEROOTKEY (or whatever), let me know and we can also  
add a check for that upstream.  To be clear, I think I'm going to do  
#1 anyway -- it's a nice way for our users to disable this stuff.  But  
I'm not opposed to having a fakeroot-specific environment variable  
check as well.
