I implemented a queue using both LISTEN/NOTIFY for notifications to the task processor and SKIP LOCKED to sift through the pending tasks in the tasks table.

I think you can eliminate polling if you don't need to retry tasks, by simply processing pending tasks at startup and then just responding to LISTEN events. However, I'm curious if there are any alternatives to polling the queue in cases where you need to support retrying tasks at a given timestamp.

> 3) OpenBSD adds pledge/unveil system calls from the browser, to prevent it from reading/writing files where it should not (plus I browse under a different user than I do other things with high confidence there will not be a privilege escalation; also they say the pledge/unveil support is easier to implement in Chrome/Iridium than in Firefox because of the cleaner separations of concerns in the code organization (my wording; though they have probably also put pledge/unveil in FF also for all I know),

Just FTR, Firefox is adding pledge/unveil support for OpenBSD in version 72, see https://marc.info/?l=openbsd-ports&m=157325338020502&w=2
