[wix-users] Can two CA's be run at the same time?

Hi Everyone,

I have a implementation question for you.  Can two (or more) Custom Actions be running at the same time?  Are they ever dispatched in a multi-threaded fashion?  There's a reason for this question.  I have a CA written that uses some global storage, and if more than one of its CA entries are run at the same time, that global usage may collide.

So, I am considering expanding this global use.  Is that OK, or should I eliminate it entirely?

Thanks for the help.
