there is still a deadlock when there is stderr output that fills the buffer

[stuzart]

if there is stderr output, even if the command successfully runs with exit code 0, the process hangs.

apparently and old issue, which was fixed with #5 - but this was merged to master rather than main so wasn't included in the latest releases

#40 should resolve this

[nickcharlton]

I've pulled out #41 from #40, and now that's in main. I'm going to cut a new release shortly, so I'm going to close this in anticipation of that but thanks for opening this.
