Hardly the only one. GNOME uses glib's g_malloc(), OpenLDAP has
ber_memalloc() etc. OTOH these wrappers usually make memory allocation
debugging harder on sane platforms because call chains are longer and
mismatches between wrapped/non-wrapped allocations only crop up when you
want to do debugging using the wrappers so you first have to chase the
bugs in the usage of wrappers before you can go after the original bug
you wanted to track down.
