What does 'persisted` here mean?

I have a reactor which is getting busier over time and I'd like to find out
where the cycles are going. Using the profiler isn't really practical on a
server running for days, so I'd like to instrument the reactor to show me which
I/O events are taking the longest to deal with.

Hi!
No guarantee it's an optimal solution, but when I wanted to inspect a
running process (which sounds like what you're doing), I had a pretty good
time with manhole. (If you're not familiar with that: it's in Twisted Conch,
and it's basically just a way to SSH in to a running box and get a REPL

Hey Jean-Paul,
For record's sake, I thought I announce here that my issue got fixed.
The problem was that I was loading the data in startService method and
it looks like there are some timers which prevent the method to block
for a longer period of time. Loading the data in __init__ of
service.Se

G'day,
So Glyph and I had a discussion about the architecture and
implementation of plugins on IRC this week, I raised some issues that
I've seen with implementing plugins in that discussion, and he said that
I should take the discussion to the list because IRC wasn't the right
place for it.

If that's the only thing you need, .ini would work fine. Another
solution would be python files with only literals, parsed through the
ast module for safety.

You can time blocking calls by instrumenting
