This is a heavily modified version of GNU
malloc. It uses
mmap as the basic mechanism for obtaining memory from the
system, rather than
sbrk. This gives it several advantages over the
more traditional malloc:
mmap, with the
mmallocfunctions using a specific heap on a call by call basis.
mmap, it is easy to create heaps which are intended to be persistent and exist as a filesystem object after the creating process has gone away.
