           Summary: slow upstart of binaries in
                    clang+llvm-2.9-x86_64-linux.tar, due to /home/duncan
                    in search path

The binaries in
http://llvm.org/releases/2.9/clang+llvm-2.9-x86_64-linux.tar.bz2, contains
/home/duncan/... in the search path for dynamic libraries.

On our Linux servers, this means a start-up penalty of about 1 second:

> strace -T clang+llvm-2.9-x86_64-linux.tar/bin/clang --version
[...]
open("/home/duncan/llvm-2.9/64/Phase2/Release/llvmCore-2.9-release.obj/Release/bin/tls/x86_64/libpthread.so.0",
O_RDONLY) = -1 ENOENT (No such file or directory) <0.131968>
stat("/home/duncan/llvm-2.9/64/Phase2/Release/llvmCore-2.9-release.obj/Release/bin/tls/x86_64",
0x7fffbd5d2310) = -1 ENOENT (No such file or directory) <0.131093>

open("/home/duncan/llvm-2.9/64/Phase2/Release/llvmCore-2.9-release.obj/Release/bin/libpthread.so.0",

stat("/home/duncan/llvm-2.9/64/Phase2/Release/llvmCore-2.9-release.obj/Release/bin",
0x7fffbd5d2310) = -1 ENOENT (No such file or directory) <0.133924>

(Maybe due to a huge number of /home directories, and therefore a slow response
from the automounter?)

Please remove the search path /home/duncan/... from binaries (in future
releases).
