AIX port

[dbwiddis]

Fixes #1166

[tausiflife]

Added few things for process. Haven't been able to test it yet.
An observation -
For process count, i think i will just query ps again to list process and count them. But if we do so as we have done for other OS, this might give inconsistent results. Lets says if in between the calls to getProcesses and getProcessCount or vice-versa, some process get killed, the output will be inconsistent.

Looking good. I don't see a problem with process count being different between queries, a user should expect that. I think I prefer counting numeric filenames in proc (same code as in Linux, and in fact it's working as-is) to a command line ps call.

ohh and btw you don't have to source .bashrc again. its fixed :)

Thank you! I was just about to ask what you did and then wondered, did I ever chmod it to be executable? Was that the problem?

i don't think executable rights was the problem. What i found was that it never ran the .bashrc file. I just created a .bash_profile and added the code to source .bashrc. You could remove the code from .bashrc and add it to .bash_profile

As i now see the thread details in ps doesn't have values. I guess it just inherits them from the parent process.

Do you know any other way of finding thread details?
