Tried to down BOARDBUSY on custom listener startup

Hi

I've written a custom perl listener for the client channel.

It seems to work quite fine when it starts properly, but most of the 
time it just sits there receiving no data and there's the message "Tried 
to down BOARDBUSY" in the listener logs.

I suspect this is related to the channel registration :)

Henrik, any clue how to debug this? May it be something wrong in my client?

Cheers,
Gildas
