At present it seems there is a 5 second timeout being enforced somewhere, from reading those JIRA at least.... I'd like to spend some more time investigating, but I have a new deadline looming for more enterprise features to carve out!!! and I have to do some more stuff on literate, etc. Hopefully something will shake out in the wash with the enterprise ssh-slaves plugin. Certainly if I find any logic or core bugs I will push them back, but unless PM decides otherwise the Non-blocking implementation is for pay customers only :-(
