We went over this some time back; the GHC runtime is wrong here, it should
only disable flags when running with geteuid() == 0. Also, the current
mechanism for specifying runtime flags at compile time is horridly ugly and
this really needs to be fixed before any such runtime limitation is viable.
I hope that will be fixed in a later point release.
