The `timeout --help` version is from a CI job:
Unexpected child output, to: getErrorStream
Child args: [cmd.exe, /c, timeout, 60]
Try 'timeout --help' for more information.
But ...\cygwin\bin is in PATH before Windows\System32
So sleep would be available, but on cygwin it is in /usr/bin.
sleep would work everywhere, except a real Windows build.
What a tortuous workaround because of a 'feature' of the VM!
