Rob Wu 097e273ca4 Improve work-around for importScripts bug.
Reverts "Hack to avoid intermidiate Chrome failures during tests."
(2b2c521213).

require.js uses importScript asynchronously, which activates the worker
GC bug in WebKit. This patch works around a bug in a way that is similar
in the upcoming (but not yet released) require.js 2.1.23

The advantage of the new work-around is that it allows the runtime to
garbage-collect idle Workers.
