Cabal and simultaneous installations of the same package

I see this as mission-critical to relieving Cabal hell.  (Am I alone?)  So it’s great that Vishal is going to work on it.  Go Vishal!

Can I take it, then, that the Cabal developers will be sufficiently involved that, assuming there are no show-stopping problems, they’ll accept the patch?

It is tantalising to me that something so critical has been so long delayed.   It’d be fantastic if it was done this summer.

For the info of all, here is the proposal:

The mentors are Ryan Trinkle and Thomas Tuegel. Hopefully as the project proceeds, Vishal will be checking in with us, asking questions and seeking clarification where necessary, etc.

Vishal Agrawal's GSoC proposal has been accepted. I guess we'll have
to wait and see what comes out of it now.
