digitalmars.D - [RFC] Modules for processes manipulation

I'd like to see in D something like .Net's `System.Diagnostics.Process` 
and friends. Reasons:

* .Net's API looks really good and user friendly

Consider these processes manipulation modules:
http://denis-sh.github.com/hooking/hooking.windows.process.html
and hooking.windows.{thread|processmemory|processstartinfo}
Differences from .Net's:
* RAII (i.e. no handle leaking)
* do not cache process properties (see Appendix)
* able to launch with argument strings array, not only command line
* able to work with process memory
     Tip: a good way to to access current process memory without 
`Exception`s thrown on failure instead of `Error`s.

Currently it misses some features and is Windows-only.
So the questions are:
* Should I add missed features for Windows realisation (i.e. is it needed)?
* Should I create a cross-platform realisation (i.e. is it needed)?
* Will it be possibly accepted in Phobos?


Appendix about .Net's `Process`:
All properties are cached. And it is documented only in MSDN article 
about `Refresh` member function. So one has to remember this fact and be 
careful with this tricky .Net. E.g. one shouldn't believe words like 
"representing the operating system threads currently running in the 
associated process" from `Threads` property docs and remember it's cached.

Yes, I know about it. That's one of the reasons my code doesn't contain 
any stream redirection as I hope we may join work.
