I am using a Lenovo laptop with 8Gb RAM, running Ubuntu and Julia v1.3-rc4. While precompiling some packages, for example OrdinaryDiffEq and my own package that depends on OrdinaryDiffEq, my machine runs out of memory with only julia, atom and a single chrome tab open. This is a huge usability problem for me, every time my package is precompiling I must be quick to close everything down except for julia, otherwise the machine will grind to an almost complete stop. I’m starting to wonder if there is something up with my julia installation that causes this or memory requirements have just gone up dramatically lately?

This rc has precompilation regressions IIRC.

Ok, that would explain why it suddenly takes absolutely forever to precompile some packages 😕
