Yes, and it seems to be an issue with cat, not mintty:

cat x           hangs
grep . x        works
cat x | grep .  works
grep . x | cat  hangs for seconds repeatedly even without ^S

Killing the cat process sometimes works (releasing mintty),
sometimes it claims "No such process" although it's in the task table (ps).
