That actually didn't work until the 0.5.0 release :)

I have no idea how to do this, but if this happens libssh is/was 
prone to hang since there are still polls without an timeout. That's 
similar to the situation you had with ssh_connect().

I actually encountered a very serious ones, that was actually 
happening with exec, but I haven't gotten access to a sample machine 
yet, so I couldn't find out what was going on. It was limited to that 
custom system though and is reproducible.
