Eliot Miranda uploaded a new version of Kernel to project The Trunk:
http://source.squeak.org/trunk/Kernel-eem.877.mcz
==================== Summary ====================
Name: Kernel-eem.877
Author: eem
Time: 6 October 2014, 4:19:05.019 pm
UUID: 0261bf17-d453-4738-924c-ed2bab916f63
Ancestors: Kernel-eem.876
Fix doPrimitive:method:receiver:args: for primitive 188
and quick methods (Object>>withArgs:executeMethod:)
and support primitive 189
(Object>>with:*executeMethod:)
=============== Diff against Kernel-eem.876 ===============
Item was changed:
----- Method: ContextPart>>doPrimitive:method:receiver:args: (in category 'private') -----
doPrimitive: primitiveIndex method: meth receiver: receiver args: arguments
"Simulate a primitive method whose index is primitiveIndex. The
simulated receiver and arguments are given as arguments to this message.
If successful, push result and return resuming context, else ^ PrimitiveFailToken.
Any primitive which provokes execution needs to be intercepted and simulated
to avoid execution running away."

"Judicious use of primitive 19 (a null primitive that doesn't do anything) prevents
the debugger from entering various run-away activities such as spawning a new
process, etc. Injudicious use results in the debugger not being able to debug
interesting code, such as the debugger itself. hence use primtiive 19 with care :-)"
