Details

We don't actually use jemalloc's build system, but we do run its configure. We should stop doing that.

This might be fixed for free if we switched to jemalloc4?

It's jemalloc4's configure we run.
Chris: we talked about this at the build meeting Thursday.
As an experiment I re-wrote some of the shell scripts jemalloc's configure uses to generate headers (jemalloc_rename.sh, jemalloc_mangle.sh et. al.) in Python, and found it reduces a significant portion of the overhead due to running this on Windows.

glandium, is moving these scripts to Python something likely to be accepted in upstream jemalloc? If so, where does their development take place? It looks like we don't maintain local patches to jemalloc in general.

I don't know, but there's no script other than shell (except autoconf stuff), so that might be a tough sale. Especially considering that adds a build dependency. Best would be to open an issue upstream and discuss the options there.

We'll make this block bug 1247781 instead, since this is entirely a configure-time operation.
