[PD] pd-watchdog question

[Ingo Scherzinger]

Since I had to have a working patch by today I was changing the problematic
patch into one big one containing all the other patches that were to be
started at startup of the first patch. This makes it kind of inflexible for
now but: The "watchdog signalling pd..." is gone.

I'm still not sure if the errors in the patch were caused by loading
problems with watchdog caused but since I've changed it any strange
behaviour has disappeared.

Generally, as soon as I start loading several (large) patches at the same
time in "-nogui" mode this happens. No problem with the graphics running.

I think I'll simply avoid loading more the one patch at the time just to
ensure things are loading correctly.

Since I'm not a programmer and really good with all that source code and
compiling stuff I'll keep my hands of that to avoid even more errors than I
had before.

If anybody wants to investigate more it would be great but I'm kind of in a
time pressure and have to get the patch I'm working on running as fast and
safe as possible.
