That should not be happening. I will try it locally.

Comment 3 by ricea@chromium.org, Feb 22 2018

Okay, I finally managed to make a working MSAN build.

It looks like it just legitimately takes a long time due to the large amount of work it does. It parses about 3000 lines of IDL. Would marking it as Slow be viable?

Mark wpt/dom/interfaces.html as Slow

The external/wpt/dom/interfaces.html test is painfully slow on MSAN
bots due to parsing 3000 lines of IDL. It's also quite slow even on a
regular bot. Add it to SlowTests.

This is step 1 to try to remove the Timeout expectation from the test.
If it reliably runs to completion on the MSAN bot when marked as slow
then I will remove the timeout expectation in a followup change.
