Welcome to 

Feature request

The asynchronous functionality of parallel-ssh is very much appreciated for management tasks. Thank you for this!

For the feature request:

It seems that the open_session() can keep worker allocated for much longer than expected in failure cases. Would it be reasonable to stretch the timeout option of wait_socket() to open_session() ?

Using Python 3.6 the example host key verification code generates the following error message:
Traceback (most recent call last):
File "example_host_key_verification.py", line 29, in
else LIBSSH2_KNOWNHOST_KEY_SSHDSS
NameError: name 'LIBSSH2_KNOWNHOST_KEY_SSHDSS' is not defined

Easily fixed by adding LIBSSH2_KNOWNHOST_KEY_SSHDSS to the imports but even then it will still not

Since it's possible to create custom session documents it should be useful to have support for that.
