        I've done my homework and perused the sources, as tradition advices :-)

        It would be so if using select(), but it seems that using poll() this limit
is avoided. Unfortunately, the Debian packaged version of pen doesn't
use "--with-poll" when compiling, so I couldn't use it. I've recompiled the
package (also updating the upstream version in Debian, 0.15, to 0.17.2) and
enabled it.

        Consider it a "beta" version, but if you're interested you can download it
from here:

        I hope my belief on poll() is true, but I'd be very thankful if someone could
confirm that it should handle many more connections than select(). Thanks in
