Hey, looks really nice! ;)

This is actually a very old ALSA-related bug mentioned in ecasound's
BUGS file. I've been waiting for the new ALSA 0.5.0 to be released.
It has a new pcm-API, so I'll have rewrite much of the ALSA code.
While doing that, I'll also try to fix this, admitedly annoying, bug.
The problem is with starting processing. Once started, no more
over/underruns. This doesn't happen with OSS drivers.

Ecasound supports (global) looping (-t:time, -tl and -y), but I guess
this isn't enough. However, adding these to ewf should be quite an
easy task. Once I get ecawave out of my hands, I'll work on this
(next month).
