------------------------------------------------------------------

Here are answers to your question

On formats:
* I will use the standard diff format - hopeful the test will pass (I have no trouble on my
side after a clean)
* I now use the block style
* I added some comments on Jsch

Other things
* The session type is now an enum (I just copied the JSch way in the first patch)
* The runtime exception was just a way to see if the code was executed at some point (removed)
* Keeping track of how many objects are instantiated is important if we want to answer correctly
to the "isReleasable" question - otherwise, opened channel will be closed when disposing of
the filesystem, unless I misunderstood how VFS was working.

I will post an updated patch soon.

PS. my time zone is CEST.

> In the software I am writing, I need to execute commands when the filesystems "allows"
it, i.e. local or via ssh (i.e. sftp filesystem). 
> For a local filesystem, I can easily do this, but for Sftp, there is no way to get a
channel different than the SFTP on, so it would be great if other channels could be open.
> I could submit a patch that would:
> 1) Allows a call to session.openChannel(String type) [following getChannel()]
> 2) Overwrite isReleaseable to keep the filesystem open if some external channels are
open
