I could be wrong but AFAIK the only restriction is that your write()
needs to return. Assuming some OS buffering, that's effectively an
asynchronous write.

Or is this special cased for terminal devices somehow? I would presume
not or most things emitting data for consumption over an ssh
connection would be extremely slow... So if it's special cased, then
empirically, it would have to be for local terminals only or something
along those lines.
