[Asterisk-bsd] Re: FreeBSD hang up when exiting * (Zeno Lee)

Greetings:

It looks like there is a bug in the zaptel driver from 
zaptel-freebsd-0.8.

It manifest itself when the zt_chan_read call is interrupted. (To 
reproduce
run zttest and hit ^C).  I first noticed it when doing a STOP NOW.

Changing the schluffen routine as follows fixes the problem:

> static int schluffen(void *q)

>         }
>         return(0);

This allows the for (;;) loop to exit after an interrupt.
