[fogleman]

That's very strange. Did you run out of memory or something? What go version?

[thejmazz]

go version go1.4.2 darwin/amd64

memory and cpu seem to be stable

[fogleman]

That's an old Go, I'd try a new one...

[thejmazz]

ah yes, with

go version go1.7.1 darwin/amd64

and then ran go get again, it works :)

My result with 1000 circles :D

Cheers.
