JavaScript heap out of memory

[drewdaemon]

I'm trying to use 0x to profile a build script that takes several minutes. It looks like the flame graph buffer pushes me over the memory limit. Would be nice if this work was done with a stream or at least if I had the option to pass v8's --max-old-space-size flag through.
