Memory leaks:

1. mount still produces 20 bytes, that I still haven't identified
2. ls -l has about 300 bytes, how do I best handle qstr duplicating?
Its name is *const char **. If I'm doing alloc() I'm breaking this
qualifier.
3. reading a file, i.e. cat has no memory leak so far according to meminfo
