OK very interesting ... is the performance benefit on certain platforms, or everywhere? A previous thread says Ninja is faster on OS X and Solaris because of it.
Though that does seem like a large number of corner cases, probably learned through painful experience :-/
It has performance benefits on both Linux (where it can use vfork) and macOS/BSDs (where it has a kernel implementation).
I tweeted a little about it here, with some perf numbers: https://twitter.com/ridiculous_fish/status/12328893907639336...
