We had a smaller third meeting and answered more issues.
Hi all,
First, thanks for writing up these reports.

Asynchronous WSGI support
-------------------------
Mostly non-existent. Fix it? Fork it? Drop it? Glyph seemed to think
we're really close if we fix wsgi.input.
Those who were present know that I couldn't understand Glyph's proposed
solution. After the meeting we worked on some details and wrote some
code (completely non-working, not even syntactically correct).
The result looks something like this:
@asyncApp
def application(environ):
yield "foo"
yield "bar"
folders = yield imapFolders()
for folder in folders:
yield "Folder:", folder
Where `asyncApp` and `imapFolders` are two functions provided by the
async WSGI container (maybe they're generalizable and can be shared
between different async WSGI containers, or maybe not, I'm not sure
yet).
In Twisted's case, `asyncApp` ends up as about 20 lines, which doesn't
seem too bad (I can share it if anyone is interested in the specifics,
it's mostly just gross generator/Deferred mangling stuff).
