PSSH is literally not parallel SSH

[jpf11]

You're actually doing ssh calls in serial.

Thank you for the feedback.
You are right. The main reason why people use pssh is that they want to execute commands on multiple servers ("parallel" is not formally a decisive factor), therefore the script was called pssh, so that cygwin user could easily find it and actually know that there is an alternative. I've corrected the description to cover the discrepancy in used methods, thank you for pointing that out.

By the way, for those needing "parallel" functionality, there is ansible package already available in official cygwin repo.
