For a large application with 1000+ shared libraries (which is how we run unit
tests here), time-to-main often *is* dominated by _dl_symbol_lookup_x.
"make && make check" are about the worst possible way to measure the impact --
they invoke small programs with (relatively) very few dynamic symbol
resolutions.
Measuring startup time for Firefox or OpenOffice would (I expect) be much more
meaningful.
