Last time I tried it didn't hang, but there was one test that took really long
time (more than all others combined). It may look like it hang (we don't pump
messages during script execution), but it's really just so slow. Be patient and
tests should go further :)

The mentioned test is slow for two reasons:
- It does a lot of string concatenations, which is slow because we use pure
VARIANT/BSTR to store them. I have a series of patches that moves us away from
VARIANT for internal data storage. Once it will be in Git, we will be able to
optimize string operations.
- We don't support indexed string access (like IE6). Long story short, this
causes strings to be 9 times longer than they should be during test run
