PPU/SPU bugs/flaws/exploits

There's a bug in the provided malloc function, if there's no heap

SPE mailbox has maximum depth of 4 messages

The depth of 4 messages for the spe in mailbox is not a bug, it's a simple hardware limitation (as you can read in this document: http://publib.boulder.ibm.com/infocenter/ieduasst/stgv1r0/topic/com.ibm.iea.cbe/cbe/1.0/Programming/L3T2H1_40_DevelopingCodeForCellMailboxes.pdf). 

Local Storage can be accessed

Well if the spe is in isolation mode only code running on this particular spe can access it's LS.

^Not entirely true, the high segment of the LS is accessible from the other SPEs and the PPE. Shuffle2 10:01, 22 April 2011 (CDT)
