Log:
OSCogVM source as per VMMaker-oscog.27.
Fix bad bug in CompiledMethod>>flushCache/primitiveFlushCacheByMethod.
Original code failed to flush the primitive embedded in the machine code
method, causing it to run the previous primitive.
Fix bad bug in the Cogit's primitiveDoPrimitiveWithArgs. Because of the
way the process primitives "return" (they don't, they longjmp) the
popRemappableOop wasn't always executed, causing the remamp buffer
to overflow.
With these two fixes things like the following now work:
thisContext runSimulated:
[(1 to: 10)
do:[:aClass| (Delay forMilliseconds: 100) wait]
displayingProgress: 'Processing...']
Nuke the unused checking primitive stack interface (shouldPopArgs et al).
