Adopt Sigar library for process management

[GoogleCodeExporter]

Sigar "provides a portable interface for gathering system information" with 
native libraries for many OSes

  http://support.hyperic.com/display/SIGAR/Home

would almost certainly be better than the current simple ProcessManager 
implementations.

Looked at it in the past but discarded due to its license; however it's now 
available under the Apache Licence v2.0.

Hi Mirko.

I have started on this refactor.
Can you have a look here

Would be great to get write access to a branch of trunk

Sigar is not implemented and ready for testing.
The latest commit breaks the API. I removed the old ProcessManager and 
implemented a new one, (SigarProcessManager).

If you want to test the old unbreakable API, you need to checkout revision 171, 
which basically is the same sigar code.

It should say "Sigar is NOW implemented".

Setting newly-added status "FixedInBranch" to be able to tell what still needs 
to be merged into trunk.

Maven can't find the Sigar artifacts; do we need to add a repository?

Downloading: 
http://repo1.maven.org/maven2/org/hyperic/sigar-dist/1.6.5.132/sigar-dist-1.6.5.
132.zip

Aah thats too bad. I have in my .m2 settings also included the jboss 
repostitory: https://repository.jboss.org/nexus/index.html

It is included there. Perhaps that's why it worked out of the box for me.
Can we ask to include sigar in the maven central? Or is it ok to refer to the 
jboss rep?

I think we can add the jboss repo to the project pom.xml.

Good idea. Do you want to do that right away?

I can add it as part of the merge - the main thing was finding out which repo 
was needed. Should be

    <repository>
      <id>jboss-public-repository-group</id>
      <url>https://repository.jboss.org/nexus/content/groups/public-jboss/</url>
    </repository>

according to http://community.jboss.org/wiki/MavenGettingStarted-Users

Great. Looks right the correct URL.

When running mvn test on the shell, I get 
INFO: connected: 'socket,host=127.0.0.1,port=8100,tcpNoDelay=1'
Mar 28, 2011 1:14:56 PM org.artofsolving.jodconverter.office.OfficeProcess 
forciblyTerminate
INFO: trying to forcibly terminate process: 
'socket,host=127.0.0.1,port=8100,tcpNoDelay=1' (pid 0)
Killed

But when running mvn test through eclipse, I don't get this and everything runs 
fine.
I am a bit worried about this. Do you know why it is killed like this?
