[PD] audio drop-outs when resizing tables??

I am still unable to reproduce it on a simple test patch; however, I've done
the following test.
I run my patch, which is a rather complex patch, made up of a lot of
abstractions, graphical interface, many send~s and receive~s, throw~s and
catch~s, a lot of tables, a few tabread~s and a couple of tabwrite~s, delay
lines, etc etc etc; a huge patch. However, it is all carefully built in such
a way that every thing that is not actually playing, is switched off, and at
any moment only a small part of the many devices are really being used; the
patch is not cpu-consuming at all.
So, while the patch is running, and almost nothing is playing (something is
playing, so that I can hear an audio dropout), and it is consuming very very
little cpu, I open a new patch window, and I create the following:
[table xxx 300000]
[; xxx resize 300000(
Just like you see it: nothing more and no connection.
Every time I click on the message box to resize the newly created table,
there's an audio drop-out.
Any idea of why?

Subject: audio drop-outs when resizing tables??
I am getting dsp drop-outs when I resize a table (say a size of 200000 or
so) if a tabread~ object exists reading from that table, even if I am not
listening to the output of the tabread~.
Even if the tabread~ is in a switch~ed off subpatch/abstraction.
Does PD recompute the whole DSP chain whenever a table (with one or more
tabread~ reading from it) is resized?
I'm talking about resizing tables by sending them a [resize( message.
I tried to isolate it in a simple patch but I couldn't reproduce it. But I
think the only difference with the patch where I am experiencing this is the
complexity of the global dsp graph, that's why I ask if the dsp graph is
