Normal sleeping threads (for instance, a thread that has blocked while
waiting for input from a queue, or waiting for a timer to finish) do not
take up any processor activity until the they are reactivated by the
event that wakes them. I think you may be working on an already-solved
problem.

Using the Unix 'mail' program, I find that the text is full of nonsense
like "3D" and "=09". I think this is an artifact of MIME encoding. Is
there any way to repost it without this stuff? Or is there a filter
somewhere handy for getting rid of it?

Resistance is futile. Capacitance is efficacious.
