That is actually more or less the same thing I already implemented. In
any case, I do of course want the module to work with ZTS mode, but
after trying to get anything to work for hours (and just getting weird
sigsegvs that didn't make much sense) I tried disabling it and it
worked.

If someone has tips/tricks on what should be done differently in ZTS
module, I would really appreciate it. I want to run PHP in threaded
mode, basically. I've tried looking in the other SAPI modules but it
didn't help me much unfortunately.
