I'm running irssi 0.8.15 (20100403 1617):armhf on a Raspberry Pi Model B with Raspbian 7 (wheezy) kernel 3.12.28+ armv6l distribution.

Ever I request a DCC streaming after accept it the screen and keyboard freezes, I am unable to type any command, even Meta + Arrow doesn't respond, but I'm using it over screen, and Ctrl + A # does work properly, that way I can see the streaming file growing.

When the streaming finishes (it usually breaks because some kind of timeout) it unfreeze and all the previous typed commands runs at once. When the timeout isn't reached it's fine, but when it is, the connection is restarted either.

I realised it only happen on lightweight hardware. I wonder it could be fixed by multithreading or sort of asynchronous file I/O solution.

Questions: U&L RPi

Edit: Even though RPi uses a SD-card I'm writing the file on a USB HDD, it should support the streaming speed but it seems it doesn't.
