I'll join this week's coffee corner talk about GC.

At ASML, Julia is now used on (part of) the machine. The machine 
is a time critical production system (you all want more chips 
right? ;), and GC was apparently one of the main concerns. They 
solved it using the manual `GC.disable` / `GC.collect` approach.

I work on hardware at ASML and am not involved with software 
development for the scanner; so I do not know any details but 
found it quite interesting to see that Julia is used in this way.
