The script works fine with Async::Scheduler from async-io gem

paddor commented 9 months ago

@bruno- Can you make a new release? That would fix this issue.

taq commented 7 months ago

I think this project is pretty dead, better use async-io. I'd just like to know if @bruno- is ok.

keithrbennett commented 1 month ago

Confirmed, as of 2024-08-27, this bug still exists.
