no, i checked to make sure - i'm using jackd from qjackctl, and i still
get the "cannot write to jackstart sync pipe 4" message. only from
qjackctl, though.  can't understand why.

i'm trying to isolate what i do when the xruns come.  jack starts is
fine until i move the mouse (sometimes) and get hundreds of xruns. 
opening alsaplayer gets hundreds more.  opening pd does not get any
(usually).  i can't figure out any consistent pattern yet.
