[PD-dev] more information on the gui getting stuck on 0.42.5

OK, more investigation brings up the following (I am including
surrounding commands jut in case I missed something):

Notice crepdtk_ping. It is almost as if create <something> got caught in
the middle of a pdtk_ping command that appears to flush the queue, so
the create <something> e.g. a rectangle command got truncated and
outputting garbage resulted in an invalid command after which the gui
stops corresponding. Disabling pdtk_ping in s_inter.c indeed disables
all GUI operations so this appears to be the culprit (as it runs in
while(1) loop and hence the asynchronous operation. I wonder if there is
a better way to invoke pdtk_ping than an apparently brute force

if (sys_bytessincelastping >= GUI_BYTESPERPING)

from the s_inter.c sys_flushqueue()?

Also, is the sys_flushtogui responsible for ensuring that whatever is
being flushed is sane? Perhaps here one needs to check that the cutoff
is indeed where \n exists?

Any thoughts?
