> Hi David , FONTCONFIG_USE_MMAP sounds interesting, I saw this too in the list of environment variables. Should I add this one?

It seems more useful, at first glance, than the others :)

I find it hard to know where to draw the line here.  Over time you could end up eventually adding everything. Would it be better to dump the entire environment to a file along-side the hs_err file?
