Actually this looks a _LOT_ more serious than on first inspection. Glibc
is doing library prelinking _BEFORE_ the application runs. Thus it will itself
open fd 2 at times to load libraries, read ld.preload and other files...
Fortunately the ones I can find seem to be read only in glibc. However I have
no idea what file handles are opened with write by other legitimate support
libraries and might end up as fd 2 when under attack
