I was preparing to integrate your solution, but I realized that I 
typically build with -j32 on my 64GB workstation. I probably still could 
use this solution but it seems like it would be very conservative for 
users with more memory available. We should open a new bug to discuss 
further, as I'm afraid this is a problem that is going to be very common 
in the ROCm stack and we will need a robust solution.

Sincerely,
Cory Bloor
