Expose a callback to allow crash server implementations to defer the uploading
of crash dumps to a later time. The client can provide a crash_id when the dump
is performed and then at a later time connect again and request that the crash

I know you said you needed to rework this. Poke it again when it’s ready for a

there somewhere else we should talk about this?

Whoops, forgot to add a way to access crash_id :)

Now it should be good to go.
