malloc() and free() are purely library-calls, not syscalls. The library 
just calls brk() and manages the newly get space by itself.

Garbage colletor is thing I personally hate sooo much - it allows 
programmers to write unclean code, makes system quite slow (thus it's 
quite inprobable it will ever go to kernel ;) ), because you have to build 
graphs of dependencies between identifiers, etc.
