hello together!

this is my first post to this list.

i stumbled upon owfs (great stuff, thanks!) while searching a simple way 
to measure and control temperatures.

i am using DS9490R (bus master) with two DS18S20 (thermo), two DS2401 
(serial) and one DS2413 (two channel switch) for testing.

after running this shellscript 24 hours (heavily switching the DS2413):

--snip--
r...@piano:/opt/1wire/uncached/3A.1EDA01000000# while true; do echo 1,1 
 > PIO.ALL; echo 0,1 > PIO.ALL; echo 1,0 > PIO.ALL; echo 0,0 > PIO.ALL; 
echo -n x ; done
--snap--

and this in parallel (reading cached temperatures from DS18S20):

--snip--
r...@piano:/opt/1wire# while true; do echo $(date +%s; echo -n " "; cat 
10.353E9C010800/temperature) >> /var/tmp/10.353E9C010800.temperature; 
echo $(date +%s; echo -n " "; cat 10.748570010800/temperature) >> 
/var/tmp/10.748570010800.temperature; sleep 8; done
--snap--

the memory consumption of owfs was about 955Mb virt / 816Mb res, and 
still growing.

owfs was mounted using: r...@piano:/opt# ./owfs/bin/owfs -uall 1wire
owfs and libow version is 2.7p17 .
configure-flags: --enable-owperl --enable-debian
kernel:  2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 
(ubuntu 8.10 amd64)

did i make a mistake, or is there a problem in owfs?

by the way: do you recommend me to use owperl instead of owfs when 
stability is the main concern?

another ting:
is there a possibility (in the 1wire-protocol in general and with owfs) 
to avoid the "blocking" of the whole bus for all other communication for 
one second while sampling temperatures using DS18S20?

im thinking of "please start sampling, i will ask for the result later".

this would be very nice when for example switching a heater via onewire 
while using the same bus with many slow sensors.

thanks a lot for your patience ;)

greetings from germany,
david
