There is another one.
Once object passes through singletonizator

Hi
Thanks for replies. It would be good to have blocking implementation.
I have to check fcntl if it works in blocking mdoe on CentOS.
Meanwhile there is Posix Semaphore made for Python:

Which one is most recommended to use for mutex alike locking to

- https://pypi.python.org/pypi/lockfile/0.9.1

Hi
Inspired by "Modifying the default argument of function"
https://groups.google.com/forum/#!topic/comp.lang.python/1xtFE6uScaI
is it possible to create singleton using construct below :
def singleton_provider(x = [None]):
if singleton_provider.__defaults__[0][0] == None:

Hi
When designing long running background process
is it feasible to monitor object/memory leakage due
to improper programming?
If it could be possible to make module which monitor and
record trends if alive objects then event can be
generated and logged if noof "zombie" objects
are to increa

Hi Community
Is there ported to Python v3 python-daemon package?
https://pypi.python.org/pypi/python-daemon/
i am afraid it is not as simple as correction of relative path input
feature and except clauses in mentioned package.
Thanks
Asaf
