 I'd like to ask if there are any plans to do the mmap() thing in fontconfig 
in the foreseeable future. I just posted a patch[*] to xdg@ mailing list 
solving the XIM problem in a similar way, so I thought I'd check the status.

 I first thought I could do the same with fontconfig, but I don't know 
fontconfig internals, and it seems to me this would be more difficult than 
XIM :( , so I'm unsure if I could get bored enough to handle this.
