both mmap and munmap), adjusting the configure script so that the component will only be activated on systems that use ptmalloc2 in the first place -- ie, Linux * Remove the malloc_hooks component - it became an unworkable solution once threads and such were considered. * Remove malloc_interpose component - it never worked quite right and was not going to be able to intercept malloc, so it wasn't going to be useful for OMPI's purposes. * Update tests a little bit to match recent memory hooks api issues - still needs a bit of work. This commit was SVN r8381.
