Description of problem:
I noticed that on my F14 32-bit system there is a package installed:
$ yum info nspluginwrapper

Once I start playing youtube flash video one of its executables, npviewer.bin,
gets activated.
The problem is that when I stop playing youtube, it still is shown in top and
contributing approx. 2-3% CPU, but also in Powertop and contributing approx.
15% to wakeups.

According to:
http://fedoraproject.org/wiki/Flash
this package is part of 32-bit installation instructions; it is even said that
... a default graphical install of 32-bit Fedora already includes both
nspluginwrapper and ...

As I understand this package is not needed on 32-bit Fedora.
So why is it included at all ?
But even if it is, why is it activated, at least under circumstance described
above ?

As a mater of fact, I removed it (there were no dependencies on it), started
youtube and all was OK.

Rahul Sundaram explained:
"It forces the plugins to run in a separate process bringing in more
stability and helps secure it with SELinux."

But, we have a problem on Fedora with excessive CPU loads/wakeups in machine
idle state, coming from different sources (kernel, user apps), which we try to
find.
When a process finishes its task in a system (here: playing flash video), it
should release its resources, assuming they are not shared by other processes.

Version-Release number of selected component (if applicable):
nspluginwrapper.i686          1.3.0-14.fc14                    fedora

How reproducible:


Steps to Reproduce:
1. install nspluginwrapper and powertop
2. start youtube video
3. watch npviewer.bin in '# powertop' and '$ top'
4. stop youtube video
5. watch npviewer.bin in '# powertop' and '$ top'
