[Twisted-Python] delay when sending data over SSH

[The Fade Away]

Hi Everybody,

When I use

channel.SSHChannel.self.conn.sendRequest

from my client application it takes between 10-20 seconds until the 
server (which runs on the same machine) gets it!

Does anybody has an idea, what's the problem?

When I open a new channel, channel.SSHChannel.channelOpen responds 
directly. I do the sendRequest after I opened the channel.

Thanks alot
Tobias
