Comment (by mascguy):

 Josh, while your update of the pool management is a nice addition, the
 9-second startup lag [due to 24 threads being spun up] is still a big
 problem. And there's no way to fix that, without being able to explicitly
 limiting the thread count.

 There's also this pesky issue, which seems improved when the number of
 index threads is capped at 2:

 * [https://trac.macports.org/ticket/69781 Ticket 69781 - portindex: multi-
 threading appears bottle-necked for 10.13, 10.12, and perhaps earlier]

 So I'm hoping you'll consider my additions as well.
