So I've been running a pkg-rolling_replace and one of the packages being
rebuilt is python3.7, and it has got stuck, apparently on an "entropy"
wait in the kernel, and it's been in this state for over 24hrs as you
can see.
The only things the process has open appear to be its stdio descriptors,
two of which are are open on the log file I was directing all output to.
This is on a Xen domU of a machine running:

It was killable -- I sent SIGINT from the tty and it died as expected.
Running "make replace" gets it stuck in the same place again, an the
SIGINT shows the following stack trace:
