Comment (by davidp):

 Replying to [comment:1 Algunenano]:

 > This means that, by default rules, it's parallel unsafe, which makes
 anyone using it also unsafe. Now, I don't know if the parallelism
 declaration is missing or it really is unsafe, but that's where I would
 start looking into.

 I didn't thing so... PARALLEL UNSAFE apply only downstream (by my
 observations). So, function marked as parallel safe is executed in
 parallel mode, even if internally calls parallel unsafe function.
 Contrary, parallel unsafe function never executes in parallel mode, no
 matter how internally called functions are labeled.

 And one correction to my original post... function default is PARALLEL
 UNSAFE, not RESTRICTED. Sorry, my fault.
