Where can I find the version of malloc that records allocation block
sizes at runtime and uses them to optimize memory allocation in future
invocations of the application?  It records this allocation pattern
information to disk.  I ask this knowing that I've found and used this
library in the past.  It has a particular use for a project I'm
working on now, but I can't seem to find it again.  The words
'profile' and 'malloc' combined produce a search result that is
totally off topic.  I've tried every combination of similar terms I
can think of with no luck.  Can you find it?

Hoard is one such library, though the performance gain with it will be
seen only in case of multithreaded applications.

Hey I just designed a new memory allocator!
