I am interested in preserving the complete PHP context for a thread (globals,
variables, interpreter, etc.--everything) for later access from a different
thread.
What would be involved in this? It seems like:
- Avoid calling ts_free_thread
- Call tsrm_set_interpreter_context from new thread
Is it safe to assume that the context of a terminated thread will not be
destroyed or overwritten as long as ts_free_thread is not called?
Thanks in advance,
David R.

I don't really know what I'm talking about, but nobody has answered
yet...
For starters, not all extensions are thread-safe. I would expect that
to mean that anything actively using those extensions saved state in
another thread is a segfault waiting to happen.
For security reasons and sheer plain cussedness, I don't think you're
going want and/or get any resource (mysql connection/result/etc, gd
images, file handles, etc) survive to the next thread. A mysql
connection, for example, is opened with a specific user/pass. Another
thread picking this up could probably abuse that, as I understand it.
Finally, your question begs another question:
Why do you want to do this?
