[Jorge Torres]

Hi Alex,

Thank you for clearing things out, Now that you show me this, it is very
likely to be a product of something I have done, and I now remember; I
noticed sometime ago that scheduler was the thread it self as you point, I
probably changed something,  I'll start  a clean  1.4.1.1  and see if I get
the same behavior, sorry about that.

Many thanks,

Jorge
