How so? Something like

for i in `seq 1000`; do
  cat /proc/self/maps > procselfmaps_`date +%s.%N`.txt;
done &

before running the problematic command? It does take a variable amount
of time to trigger, and sometimes exhibits as a complete freeze instead
of an error. What should I be looking for here?

I already have a Windows Defender exclusion for my Cygwin installs.
Turning off real-time protection temporarily didn't help.

Good idea. Tried it, didn't help.
