How long does "make test" typically take to run ?

It is at "running: test_threading (4 hour 24 min)" 

I also have a change to, only including the relavent
section as line numbers have changed for the rest of the patch.

There are three build cases.

  Have /usr/include/uuid.h
  Don't have /usr/include/uuid.h so need pkgsrc devel/libuuid
  Have /usr/include/uuid.h but pkgsrc devel/libuuid is installed already.

I had not tested the third one before sending the previous email, I
don't have devel/libuuid on my -current systems.

Also need to compare between Python-3.7.3 and Python-3.7.4
before we patch them. The change log suggested that there was a
difference in how the uuid module config was done.
