malloc() sucks

C programmers think memory management is too important to be left to the computer. Lisp programmers think memory management is too important to be left to the user.

discuss!

I have a global hash table; malloc(a) stores a in that table and returns a unchanged; free(a) removes a from hash table. This way, even with garbage-collected language I can use manual memory allocation; garbage collector won't touch anything until I free it (and I malloc and free everything).
