This doesn’t work well because it’s not something that pip is going to be

to disable the automatic use of pyOpenSSL for this reason too. The only C
stuff that pip can reliably use is the standard library.
Ugh, I'd completely forgotten about that limitation of Windows filesystems.
And the main alternatives I can think of involve copying files around
as pip starts up, which would be unacceptably slow for a command line
app :(
