In the AJC ecmascript library that is included as a package in IDM4
there is a comment related to the writeLog function. I'm assuming the
comment is from Shon Vella (as he's listed as the person who ported this
from Java). The comment states "Unlike the original AJC, this function
is not thread-safe - I think this can be fixed"

My questions are (especially to Shon), what makes it not thread safe?
For very low volume usage is it risky to use this? Also, any suggestions
on how can this be fixed?

I'm not much of a Java programmer, so wondering if anyone else can comment.
