A single close(fd) syscall is cheap, but when MAXFDS (maximum file
descriptor number) is high, the loop calling close(fd) on each file
descriptor can take several milliseconds.
The default value of subprocess.Popen "close_fds" parameter changed to True
in Python 3. Compared to Python 2, close_fds=True can make Popen 10x
slower: see bpo-37790 [1]
The present workaround on FreeBSD to improve performance is to load and
mount the fdescfs kernel module, but this is not enabled by default.
This change adds minimum viable (and upstreamable) closefrom(2) syscall
support to Python's subprocess and posix modules, improving performance
significantly for loads that involve working with many processes, such as
diffoscope, ansible, and many others.
For additional optimizations, upstream recently (3.8) landed posix_spawn(2)
support [3] and has stated that they will adopt close_range(2) after Linux
merges it [4]. Linux/FreeBSD developers are already collaborating on
ensuring compatible implementations, with FreeBSD's implementation pending
in D21627. [5]

ports r393217 via bug 200622 [1] originally set MAKE_JOBS_UNSAFE=yes due to
incorrect uses of recursive make [2], causing intermittent build failures when
run with multiple jobs (-jN).
Upstream committed a fix for the issue in default (3.6, at the time), 3.5 and
2.7 which are now contained in all released lang/python?? port versions. 3.4 did
not receieve a backport merge.
lang/python3.5+ ports inadvertently inherited MAKE_JOBS_UNSAFE=yes, via
repocopies from lang/python34 on their creation, when they were infact safe to
use with -j.
Remove MAKE_JOBS_UNSAFE in all lang/python?? ports except python34 accordingly.

When python3.?-config is symlinked to another location it starts
outputting bogus paths. For example
$ pwd
/home/tobias
$ python3.6-config --includes
-I/usr/local/include/python3.6m -I/usr/local/include/python3.6m
$ ln -s /usr/local/bin/python3.6-config python3-config
$ ./python3-config --includes
-I/home/include/python3.6m -I/home/include/python3.6m
This breaks ports trying to use BINARY_ALIAS together with
python3.?-config. Apply a patch to resolve the symlink first before
trying to find the install prefix.
