None of these things are useful for Firefox. All of these things are used by Thunderbird. So, Thunderbird's S/MIME support will need to adopt the missing functionality in comm-central. Note that all of these functions do I/O on the main thread.

Presumably there's some existing APIs that S/MIME can hook into that are async? At a quick glance, I didn't see them, but maybe I'm looking in the wrong place. If we do need some additional async apis, then we'll need a bug for them. What's the people tab actually used for? I've never really looked at it before today, is it useful for anything?

There are a few things in PSM that I would like to remove from PSM, but which is needed by Thunderbird, including this stuff and others. I think the best solution is to simply create a new component in mailnews that can expose these mail/news-specific things. Then, we don't have to bother with converting them from sync to async unless/until it becomes a priority for Thunderbird. > What's the people tab actually used for?

The people tab seems to be for the S/MIME certificates that the user has stored by extracting them from email received from those people. I think it may be useful to mailnews users but it is just confusing to have it in Firefox. I don't know much about XUL, but I think this is something that we can do by removing the tab from PSM and then having mailnews add it back with a XUL overlay or similar.

Yes - as pointed out by Brian, it allows you to view/manage the certificates which have been automatically imported from signed messages (http://hg.mozilla.org/mozilla-central/annotate/69008b1fd6eb/security/manager/ssl/src/nsCMS.cpp#l255). It also allows you to import a recipient's encryption certificate from a file ("Import..."), and it's the only [GUI] way to delete expired mail recipient certificates from the cert database. I agree that removing it from Firefox makes sense (I can't think of a situation where the browser really needs this tab). Note that the "People" tab is already in a separate overlay (http://mxr.mozilla.org/mozilla-central/source/security/manager/pki/resources/content/OthersOverlay.xul), so it shouldn't be too hard to make it mailnews-only. Bug 164707 might be helpful for determining what changes are needed (these happened when the "Other" tab was added - now it would be about reversing this for the "People" tab).
