So far every example that I've seen in the ongpoing bulk -a I've
got in process is doing (via an example: cargo-c):

|   `-- /usr/bin/make -C /usr/ports/devel/cargo-c build
|     `-- /usr/local/bin/cargo build --manifest-path
/wrkdirs/usr/ports/devel/cargo-c/work/cargo-c-0.9.2+cargo-0.55/C
|       `-- /usr/local/bin/rustc --crate-name im_rc --edition=2018 

There can be multiple cargo subprocess instead of just one /usr/local/bin/rustc
.

The process getting the huge CPU time is the one running /usr/local/bin/cargo .
For example:

342:31.37 /usr/local/bin/cargo . . .
 33:21.39 /usr/local/bin/rustc . . .

Given the (effectively unbounded?) number of messages about pthread_peekjoin_np
that seem to be accumulating in the log files, the problem may be tied to cargo
vs. its subprocesses.
