pub(crate) const PIX_EVENT_DISPATCH_CONCURRENCY: usize = 64;Expand description
How many PIX share resolutions may be dispatched into the SessionManager at once.
A dispatch can block: lifecycle events are delivered to a per-session supervisor over a bounded channel, so a session whose supervisor is busy backpressures its sender. All sessions share this one stream, so dispatching sequentially would let one such session hold up PIX progress — and therefore the pipelined next-SSA request — for every other session on the node.
