"niceload --process" doesn't work after rewrite?

[Assaf Gordon]

Hello,

I'm having trouble getting "niceload --process" to work (with any version 
released past 2011-10).

Is it possible that the complete rewrite of July-2011 missed this functionality 
?

A quick look at the source code shows that in version 2011-03-22, the variable 
"$::opt_pid" is passed on to the "$processid" variable, whereas in later 
version the "$::opt_pid" is never used (except once, to skip a loop, but not in 
the actual "Process" object).

Or am I using it wrong ?

Suggestions are welcomed,
