Temporary withdrawal of large (> 1GB for RAM) tasks!

During the last weekend it has become clear that the big workunits (~ 2GB for RAM) in our BOINC-project were run in a very inefficient way:
- we obtained only 60 positive results from> 2000 tasks sent and they were from from Linux-machines only;
- they required large resources when the number of large workunits per machine was > 1 with blocking the RAM;
- they create bottleneck and do not allow small workunits to move to those volunteers who have less powerful machines.

Reasons?

Previous ones are as follows:
- incorrect temporary memory addressing for > 2GB in our clients for Windows,
- conflicts with system calls in Win 64-bit systems (this is fixed).
So we decided to cancel and return to them after more effective optimization and elimination of such bugs.

But we are grateful to those who managed to perform successfully these large workunits - they will be used by us!

Many thanks to re_SET, varador, Saenger, zombie67, DEATH, and many others who sent us their reports, observations and suggestions!
These conclusions and corrections have become possible only due to your help!
