1600605 - Add support for prio(medium-high) or some such to ipdl

Status: RESOLVED FIXED

(Core :: IPC, defect, P2)

Description

[Olli Pettay [:smaug][[e-mail]]]

prio(high) is for vsync, prio(input) for input events.
Normal priority messages are therefore used for most of the messages.
But there are cases when higher-than-normal priority could be useful -
in Fission at least load events.

Assigning a priority so I won't get yelled at by the bot.

The ipdl code around priorities is rather error prone, but I'll just copy-paste what has been done with high priority.

Attachment: Bug 1600605, make PNecko to use mediumhigh priority messages, not high priority, r=mayhemer

Per comment https://bugzilla.mozilla.org/show_bug.cgi?id=1442178#c54 I'm using this PNecko as an example case
for this new priority.

Depends on D57013

Tracking for Fission riding the trains to Beta (M7)

Blocks Fission page load performance work, but doesn't block enabling Fission in Nightly (M6).
