[PD] Worse performance with -nogui.

Hi Mario,

I think you might be being bitten by this bug, though I'm not 100% sure.

Some versions of Pd have a bug where the sample rate isn't set correctly
during initialisation before loading patches.  This can cause all kinds
of strange problems (delay lines having the wrong length, externals
crashing...).

A workaround is to load your patches using a loader patch like
[loadbang]-[delay 0]-[;pd -open your-real-patch.pd path/to/patch(
The attached onload.pd provides a more general approach, but needs at
least pd-0.39 (December 2005) to work properly.

As you can see in this test log, Miller's pd 0.41, 0.42, 0.43 have
problems - earlier and later versions seem fine.  I couldn't test any
pd-extended versions (someone with a few versions installed wants to
try?) but pd-l2ork git master is buggy too.
