Twisted itself (all parts of Twisted, not just Twisted core) does not use
inlineCallbacks because it requires syntax only available Python 2.5, and

I'm trying to figure out how to reduce the CPU load of an app. I've
already done a lot of profiling and have trimmed a lot of fat, but we're
still not getting as much throughput as we'd like. We

Not as much as consistency and coherency.

Nope.
If you want to
perhaps try to defer to a separate process?

I think that nice syntax contributes towards adoption. Subclassing
deferred and adding a __get__ function that queues calls for future
Deferreds is at least worth a shot. Perhaps adding a safety net with
allowed function names would help. This list could be per "project" -

That is kind of what I found. In my app I basically have the following
triggered using callLater:
do a select and create a new SSL connection for each item returned
Wait for the response
Do between 2 and 4 inserts depending on results
Close the connection.
As measured in connections completed pe

It's a replacement of standard python socket module. What make it
different is that this module only blocks a tasklet, not an entire
Python thread.
With this module and stackless python, theoretic

Depends how long it blocks for, and what else your process is doing.
With the reactor blocked:
* no socket reads or accepts can be done
* no callLater or Loopi
