Depend on parking_lot 0.10

[dvtomas]

New version of parking_lot has been released, and I'm getting clashes between my project depending directly on 0.10 and serial_test depending on 0.9. Compilation fails with "Perhaps two different versions of parking_lot are used?"

Maybe serial_test should be updated to depend on parking_lot 0.10 as well?

Possibly. Only problem with that is that you then get Amanieu/parking_lot#188 pulled in, which means our MSRV has to jump to 1.36. If rust-lang/rust#65262 gets resolved at some point I could leave the version floating a bit more, but for the moment this is slightly annoying.

I'll probably just bump the MSRV and do a 0.4.0 release at some point however.

Hey,
thanks for upgrading parking_lot. Do you plan to release new version to crates.io anytime soon?

I'd been delaying because this and #17 turned up relatively quickly after one another and wanted to wait and see if anything else cropped up before doing a new release, but looks like we're safe for the moment so I'll do that
