A Few Newbie questions

[Lonnie Cumberland]

Hello All,

I have been watching Wine grow over a period of time and it looks like 
things are getting better each time that I visit the site.

Let me first say "GREAT JOB" to all of the developers on the project.

I am wondering a few things and hope someone could take a stab at 
answering these for me.

1.) Is wine thread save and can I run many instances without problems?  
Also, can multiple users be running multiple instances without major 
degrades in system performance for each instance?

2.) What is the main differences between the WineX and Wine 
developments?  Which is more stable?

Thanks in advance,
Lonnie.
