This is jsonrpc2_v2, and it's closely related to the rest of the cluster of jsonrpc2_v2 concurrency bugs (such as #46520). I have a (rather large) stack of CLs that should fix it, but I've been having a hard time focusing enough to get that stack ready to merge. 😞

(The concurrency bugs reproduce more readily on OpenBSD, but they're present on all platforms and can be reproduced with a high enough -count.)
