okay, i'm bringing back a thread from a year ago. for mod_parrot, i'd

which confirms the offending code, but it doesn't offer much explanation.
btw, i'm working off a CVS update from last night.

Let's asume for a moment that it's easy to build a miniparrot for
ethier the host or the target.
The first phase would run on the host and prepare the tests and a
miniparrot for the target, but not run them.

Think about tied values. When does STORE get called, precisely, on a
tied target of s///? It's good to be explicit about this, down at the
C API level, just so we know what to optimize for. The final answer
is proba

I am vaguely familiar with Topaz and a google search turns up a great

Is there somewhere I can find a postmortem of what went wrong/why the

1. can you still dlopen the running image by passing a NULL string to loadlib?
No. Didn't work that way, IIRC
2. can you dlsym (via dlfunc) a statically linked function?
Yes. Pass NULL for the library PMC:
