Should fix usage with bundles including bunyan and using strict mode.
Had to fix a surprise effect that 'window === this' is no longer
true in strict mode:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode
"""That means, among other things, that in browsers it's no longer
possible to reference the window object through this inside a strict
mode function."""
Fixes#236, #231, and #223.
The test suite for this is a bit finnicky because root rights are
required to run dtrace. By default we run the dtrace.test.js file
with 'sudo'. Use this to skip the dtrace tests:
SKIP_DTRACE=1 make test
Note taht 'make test09' is busted because dtrace-provider seems
busted with node 0.9.1 at least.
