Libmallocjack
=============
This is a work in progress, it was barely tested only on glibc-2.27 and
still lacks thread-safeness.
Compilation
-----------
To compile the library run `make`. To run the tests `make run`. Remember to
compile the code you want to debug with `-rdynamic` and `-funwind-tables`,
besides naturally your basic debugging options. When not compiled with the
last two compilation flags though you won't get string symbols for functions.
Built-in modules
----------------
### memstat
Print overall process and function statistics.
### memlimit
Limit memory usage by process and function.
Todo
----
* [#a] enable thread-safeness everywhere
* [#a] use mmap in local_alloc and support free
* [#b] port memstat to gnu malloc info api
* [#b] detect huge page, segregation and brk/mmap
* [#b] allow dlopen() specific targets
* [#c] check malloc_usable_size() consistency
* [#c] add strace-like debugging primitives
* [#c] add ltrace-like debugging primitives
