@comdiv can you add nocache support for jspm_packages dir as well ?
Without that karma crashes on OS X because of too many opened files at the same time.

Adding the following line:
jspmPattern.nocache = jspm.nocache;
after this one and specifying nocache: true in options helps.

Can you please add this feature to your PR? (I can do own PR but just don't want to multiply PRs)

[comdiv]
