[pypy-dev] What is ABORT_ESCAPE?

[Maciej Fijalkowski]

ABORT_ESCAPE means that the virtualizable was accessed from outside
the JIT during tracing. This is a big no-no, virtualizables are meant
to be used *only* from the JIT and not from the outside. If you look
at the trace up to that  point, it should be relatively obvious what's
happening (e.g. something is a call and not inlined). The trace is an
argument to the JIT hook.
