----------------------------------------------------------------
Reverting the commits of this issue because they are causing higher memory
pressure. Due to this, our Travis builds are failing because we don't release
the unsafely allocated memory blocks fast enough:
master: 676b53fe799374aa9e86ce65a12bc788a5b42f2f
1.10.0: 1c57e8ec31b0dd6fe873ee17f2437f091364744a
I guess this means that we should monitor the unsafe memory usage and try to
recycle freed segments when requesting new segments. This will prevent the
accumulation of unused memory segments which causes memory pressure.
