 Well it's fairly easy to do a simple benchmark of how much time glibc
is taking to startup, take two /bin/true programs one in C and calls
glibc exit() (linked static and strip'd) and the other in nasm from
http://www.muppetlabs.com/~breadbox/software/tiny/teensy.html

% time perl -e 'for my $i (1..10_000) { system("/tmp/test", "");}'

 test == nasm
0.46s user 4.16s system 99% cpu 4.631 total
0.50s user 4.09s system 99% cpu 4.596 total
0.45s user 3.93s system 99% cpu 4.388 total

 test == glibc, static striped
0.89s user 5.35s system 98% cpu 6.362 total
0.71s user 5.46s system 99% cpu 6.183 total
0.96s user 5.26s system 99% cpu 6.233 total

test == glibc, static
0.95s user 5.20s system 99% cpu 6.159 total
0.77s user 5.44s system 99% cpu 6.217 total
0.84s user 5.32s system 99% cpu 6.178 total

test == glibc, dynamic
