I would like to request a change of the Packaging Guidelines, advising
packagers not to interpose malloc.

The use here of 'interpose' is unclear to me -- are you saying
'substitute a different' ?

The reasons are:

* We have resources to support glibc malloc, but not for other mallocs.
* Other mallocs  do not follow ABI and provide insufficient alignment.
* Choosing a malloc is workload-dependent and forcing a non-default
   malloc takes options away from system administrators.

Could you please mention a couple of bugs where this is shown?
