Re: Get exit code of a executed remote command

["Oliver Stöneberg" <oliverst@xxxxxxxxx>]

The function is quite flakey, because of issue in the way the close 
flag is handled internally. I had to do two things:

1. call ssh_channel_close() before you call 
ssh_channel_get_exit_status()
2. put ssh_channel_get_exit_status() in a loop and wait for the 
result to be not -1. I am waiting 20 times 50ms.

This have been very reliable in using it with dozens, maybe even 
hundreds or thousands of machines in the past few months.

As a side note, you might also run into this problem with buggy SSH 
daemons. There was apparently a dropbear version, that didn't always 
send the exit status.
