Tracking SharedArrayBuffer status

[mulderr]

Due to Meltdown/Spectre all major browser vendors are temporarily disabling SharedArrayBuffer by default.

• Chrome
• Firefox
• Edge

Importantly:

This is a temporary measure until other mitigations are in place.

Until then this breaks nanosleep which is using SAB explicitly.

According to the information here:

SharedArrayBuffer will be re-enabled in Chrome versions where Site Isolation is on by default.

Chrome 67 seems to have site isolation on by default and link below suggests Chrome 68 re-enables SAB. (yay!)

Some comments here suggest Firefox does not have a plan yet but they are discussing it. Until then SAB has to be enabled manually.

Edge... do we care?

Closing. Firefox may still take a while but new versions of Chrome should work out of the box so there's an easy solution to point people to.

Great news. I'm pretty hopeful that this will be on by default in every major browser within the year, so I don't mind closing this.
