Yes (except lapack wrappers). This was decided some years ago when most of us
had single CPU computers and then the idea was that using
`threadsafe` would add unnecessary overhead. Nowadays,
I guess, all f2py wrappers could have threadsafe enabled.

What do you mean? Currently only lapack wrappers in scipy use threadsafe
and there has been no attempts to use it elsewhere in scipy, awaik.
I don't understand whether you consider it as a bad or good thing.
