Subject: Re: [Patch] Updated version of emutramp_enabled_check() for PaX kernels

Hi Magnus,

  Reading /proc/self/status is a little more heavy weight than
checking an environment variable.   Do we really have to do this every
time we call dlmmap(), or can we do it once
and cache the result?

Thanks,

AG
