The issue I'm seeing is that the ~million DeferredSemaphore.run() calls are
inefficient; it's independent of list/generator.
First off, have you read http://jcalderon
The background:
I've been using DeferredSemaphore and DeferredList to manage the running of
tasks with a resource constraint (only so many tasks can run at the same
time). This worked great until I tried to use it to manage millions of
tasks. Simply setting them up to run (DeferredSemaphore.run(

Sounds like your project would be appropriate for twisted. You'll have the
easiest time if the reading and writing can each be implemented as a
separate process (independent of other jobs on the machines). Be sure to
read the following documentation:

Your traceback went to stdout whereas you were probably watching stderr or a

We're also moving to python 2.6 (the change is really Debian 5 to Debian 6).
Should it would work in 2.6?

r, is there an obvious flaw? In particular, can I get the
SIGCHLD handler using signal.getsignal, then call it via my "super" handler?
I don't need to do any special handling of SIGCHLD, so I could just leave
that signal handler alone.
All thoughts appreciated.

This is especially important if you start any processes from twisted

#x27;s,
especially the Tutorial/Library Reference/Language Reference breakdown.
Users tend to know the level of understanding they are looking for and
Python's documentation reflects that.

ead to jump to the front of the queue of

callFromThread, would the call simply be delayed until the thread
round-robin got to the reactor thread? Or, without wakeUp, is it possible
the callFromThread call would never be made?
