830694 - [OS.File] Use zero-copy transfer between workers

Status: RESOLVED FIXED

(Toolkit Graveyard :: OS.File, defect)

Description

[David Teller [:Yoric] - still alive but not very active]

At the moment, some transfers do not take advantage of Transferable objects (http://www.w3.org/html/wg/drafts/html/master/infrastructure.html#transferable-objects). This makes them extremely slow.

We should fix this immediately.

Canceling to get this out of my queue.  There seem to be some bits around Transfer that are missing from this version, as we discussed on IRC.

This version makes a lot more sense, yes. :)
