[RC5] Possible proxy/linux client bug.

Hello!

Seems like we are calculating the same blocks twice here.
I have set 2^30 as blocksize and are using the Amd-486 core on 
one cpu, and the 486 core on an other.
For the AMD 486 core i get the block 00017CFB:80000000 being processed
first as a 2^31 block and later as a 2^30 block.
For the 486 core i get the block 00013711:C0000000 being processed
twice, 
both times as a 2^30 block. (see logs below)

Perhaps this is a proxy bug that is already fixed, so the effect
will go away when i get new blocks.

regards, Thord Nilson.

P.S:

A "grep Completed" on the .381 client log gives the following pattern:
