With synth you can reduce the number of workers to just "1" (ie:
Number_of_builders=1), if you just want your ports-build to complete
without any stress. However, one of the reasons why I use synth is
_because_ of the stress it can place on my 12-STABLE snapshots. If the
system is stable and performs well when under load, I feel just that
bit more assured about using it in production environments.

My 2 cents.
