The plan is for the next major release of Interchange (probably
Interchange 6.0) to fully support threaded Perl. There's nothing we can do
about the performance problems, so serious Interchange users will likely
keep using unthreaded Perl builds. But we want to make it easy again to
get Interchange installed.
Until that next major Interchange release, you can try to use a threaded
Perl, but we still recommend using a nonthreaded one.
