I just tried building samba47 here.  Top shows python spending a lot of
time in that state and steadily growing in size, but forward progress
does happen.  I got a successful build:
  [00:07:54] [01] [00:06:31] Finished net/samba47 | samba47-4.7.4_1: Success

I'm currently running:
  FreeBSD 12.0-CURRENT #0 r327261M: Wed Dec 27 22:44:16 PST 2017
