Subject: Re: rake with net/ssh = problems?

     shell = session.shell.sync

session.shell.sync gives a shell whose shell commands appear block and
synchronize when command completes.

    out = shell.pwd

out is a (net/ssh) struct, and stdout is a string member. From my irb
session:

irb(main):002:0> require 'net/ssh'
=> true

irb(main):003:0> s = Net::SSH.start('svr.com','usr','pwd')
=> #<Net::SSH::Session:0x7ebb040 @host="svr.com", ........

shell = s.shell.sync
=> #<Net::SSH::Service::Shell::SyncShell:0x80552a8 .....

out = shell.pwd
=> #<struct Net::SSH::Service::Shell::SyncShell::CommandOutput
stdout="/a/directory/location\n", stderr=nil, status=0>

irb(main):006:0> puts out.stdout
/a/directory/location\n
=> nil

But in the rake task version 'out' is a string showing my current local
directory!
