Hi Armando & Claudio,
I tested your latest patch, unfortunately it still doesn't work for me.
I applied the patch to the current trunk, copied my algorithm code and
ran it on the cluster. If it runs in memory, everything works well. If I
enable out-of-core I run into the deadlock as before.

A superb source of datasets is
Stratosphere even employs its own memory management by serializing data

different buffer implementations to gracefully spill to disk.
