I've just committed it:

+ added new function hb_xclean() executed by GC just before resuming
suspended threads - it can be used by memory manager to clean
internal structures and release unused memory to OS.
% release unused memory to OS in hb_xclean() when DLMALLOC is used
% release unused memory in all mspaces to OS in hb_xclean() when
HB_FM_DLMT_ALLOC is used
% release unused memory in mspace when last thread detach it
% balance used mspaces between threads in hb_xclean() when
HB_FM_DLMT_ALLOC is used
Please look at it. I think it should address most important problems.
We can extend it and detect thread activity (number of allocations in
given mspace) for better mspace balancing but it will begin to be
really more complicated. Now it's still very simple.
best regards,
Przemek
