The push active context bytecode is very cheap in Squeak. This isn't
true in VisualWorks. That's because Squeak doesn't have VisualWork's
context cache stack. We pay with slower sends but gain in simplicity
and fast access to the current context.
Have a look at Interpreter>>pushActiveContextBytecode.
I'm looking at adding a new context type to represent compiled blocks
at the moment. That's why I'm spending this weekend digging through
how blocks currently work in 3.8.
