Hmm. Did anybody measure the performance increase in a "typical"

In the current issue, it is not that much a question of performance,
but of correctness: the two versions of libstdc++ aren't mutually
binary-compatible, so Debian needs to decide whether to support i386 or
compatibility with other distributions (and thus likely upcoming jdks
etc) - you can't have both.
