In trac.web.main.py line 482 says:

if env and not run_once:

If I get this right, it performs cleanup / shutdown although the environment is to be cached.

In our test environment I used inverted the condition and trac works much faster (approx. -1 sec. ticket loading time) and had no negative side effects (mixed up sessions, increased thread count, increased memory usage etc.) till now.

This is what I did:

if env and run_once:

I think the general idea with run_once is that all will be cleared when the app exits its single run, so nothing in particular to worry about at intermediate stages.

For the env.shutdown() call the major tasks performed is thread-local cleaning of the db and repository pools - which sounds like a good idea to me. However, if this cleaning requires a full second for each request, then certainly the code should at least be reviewed to make sure we aren't too agressive when thread-cleaning.
