-    Don't trust closefrom() on Linux.
-    
-    glibc's closefrom implementation does not work in a chroot when the kernel
-    does not have close_range.  It tries to read from /proc/self/fd and when
-    that fails dies with an assertion of sorts.  Instead, call close_range
-    ourselves from our compat code and fall back if that fails.  bz#3349,
-    with william.wilson at canonical.com and fweimer at redhat.com.
