Performance: App is sometimes slow to close (takes several seconds)

[dbarnett]

I've noticed the app is surprisingly slow and in some cases even takes several seconds to close after I click the X button.

There's no noticeable delay if I just open the app, wait for the main UI to load, and then click X. If I start a SQLite connection and then close the app, it does seem to consistently hang for a couple seconds (which could conceivably take a little time to close a DB connection, but still feels excessive taking several seconds in the case of a local SQLite file). But also even if I just start the connection dialog for a SQLite connection, quit out of the file picker, and close the app, that still seems to take the same several seconds to exit... in that case I can't imagine why.

Are you in dev, debug or build mode?

[dbarnett]

I noticed it from the installed deb downloaded from the site and then reproduced similar in dev mode.

I can definitely dig deeper into causes later, just noting some observations for now.

Initial thoughts without testing anything, I think the problem might be in the logic of cleanup, specifically while killing the sidecar command child.
