---------------------+--------------------
 I'm installing MacPorts on a PPC macOS 10.4 in qemu and `portindex` has
 been running this command for 3 hours already:

 `/opt/local/libexec/macports/bin/tclsh8.6 /opt/local/bin/portindex
 /opt/local/var/macports/sources/rsync.macport`

 I'm new to MacPorts and tcl, so I don't understand what the `portindex`
 script does. I did, however, notice that it sets up a worker pool.

 If it's CPU-bound, perhaps it'd be faster to avoid threading and mutexes
 on single-core machines, such as the G4 that I'm emulating?
 I don't actually know whether that's the bottleneck, just throwing the
 idea out there.
