Hey Thomas,

thanks for the tip.  but there seems to be some probs with the code.

i noticed in your thread2 example that it doesnt really stop the thread.
at least not on my machine.  I open a test patch with thread2 object and
it looks like this with 'ps afmx'

|       \_ pd -noadc thread.pd
|           \_usr/local/lib/pd/bin/pd-gui 
|           \_ pd -noadc thread.pd
|               \_ pd -noadc thread.pd

if I delete the object on the canvas or even close the patch by clicking
on the "close" icon from the Window Manager (window maker),  it still
looks the same as above with 'ps afmx'

with readanysf~ , I am now using the ShouldExit() check in my while
statement.  If true, I clean up and return.  Funny enough, if I delete the
object from the canvas, it WILL stop the thread...or at least it goes away
with 'ps afmx'.  But, if I click the patch away (close it without deleting
the object first) the thread seems to stay alive. 

hmm - august.
