Hi -
it seems that one can't just switch the malloc() implementation
anymore to compare or track down user program problems: jemalloc
provides posix_memalign(), and userlevel programs are picking
it up, while phkmalloc doesn't support it.
So what to do --
-implement a (probably less effective) posix_memalign() on phkmalloc,
-add an option to jemalloc to desist from using memory above sbrk()
 which might be enough to check whether this is a problem for
 the user program, and/or
-state that phkmalloc is depreciated and no binary compatibility
 can be expected

best regards
Matthias
