This code is a slightly changed version of the
libcollections. For the original version see
The only difference is how memory is allocated. Specifically this versions allocator uses file-backed memory (effectively swap).
This is probably a bad idea, but could be useful in situations where you plan to allocate huge HashMaps, but do not want to depend on your systems swap. There might be several reasons for this:

You do not wish to minimize the performance impact of running the code, but not forcing other processes to swap and drop their caches as the
HashMapclaims all your memory. I have not tested how well this works in practice.
Right now this only works on Linux 3.11 and higher, since it uses the
