this was implemented using a chain (tree followed with pipeline) by setting the chain fanout to a factor of size etc but the chain datastructure was fixed in length and if exceeded the topo create returned a null which isn't helpfull in cid next function of comdup...
Anyway two fixes, first we do have a real linear function so changed the decision function and second altered the
topo chain create to force chain fanouts of less than 1 to 1 and fanouts bigger than max to max.
next check in will change chain to dynamically allocd array (reallocable) but we shouldn't ever use a chain fanout for a linear tree anyway.
(lession must rerun all tests for all data sizes when changing decision functions)

As the common part is the one that create the shred memory file it seems
logical to make it destroy the file as well. Therefore, the code for
unmapping the file is in a common place.

On some systems (like windows) qsort can modify the order of modules when the
comparaison function return 0. As we expect to have the
mca_btl_sm_add_procs_same_base_addr called before mca_btl_sm_add_procs we have
force the qsort to return the SM modules in the correct order. Giving to the
same_addr module a slightly higher priority solve this problem.

"ln -s" on all Unixes and to "cp -p" on windows).
When we remove an executable use the correct extension for its name
(add $(EXEEXT) to the name).

(apparently we've been doing this in opal and orte, but not in ompi
yet). All public symbols begin with "ompi_coll_tuned_" (not
mca_coll_tuned_) except the component struct. Now this component
passes the illegal symbol report with no hits.

the baseline collective component. Please report any problems with
this component.
If you run into problems with this component, you can disable it with:

confuses the Lahey compiler (because it doesn't want to name a module
mpi_kinds.ompi_module). We shouldn't need this because we're already
touching a sentinel file (mpi_kinds.ompi_module) for make
dependencies; we don't need the compiler-generated module to be named
that.

deallocation came from the allocator (malloc, fee, etc) or somewhere
else (the user calling mmap/munmap, etc). Going to be used by Galen

current_op is not thread safe!
