Perhaps someone with a bit more familiarity with the Parrot IO subsystem
could give me some guidance here. I'm currently trying to get a new
'peek' opcode working, and I'm having difficulties getting the io_unix
layer implemented correctly.
As far as I know, I'd get a call down into the io_unix

Great.
The bug (and other reported curruptions) are definitely coming from the
COW logic in register.c. This is what happens:
Setting up the exception handler (which is a continuation) triggers COW

This is unlimited self-inspection and self-modification :) With little
additions (nested structs) one could read/write all Parrot_Interp

I expect the following code to print out a single colon (since
PerlUndef prints as the empty string) and a newline. Instead, I get:
:get_string() not implemented in class 'RetContinuation'
which shows that the PerlUndef I assigned

Yes, the problem is the child process can't inform the parent of how many
tests it ran. The simplest way around this problem is to have the
parent account for any tests run in the
