2.2 is unfortunately now "ancient" in open source years, and since 2.4
involved large rewrites, it's not clear that any bugs you find in 2.2
will still exist in the current version.

Nope, but it looks like they're all crashing inside the GType system.
It's possible that if you create at least one SoupSession first to
initialize/register everything before creating others in parallel, then
the parallel creations after that won't crash.

(Also, it's a little weird to be creating lots of SoupSessions in
parallel anyway. Most applications will only need one SoupSession, and
you can use a single SoupSessionSync from multiple threads.)
