We need to write microbenchmarks and do more careful analysis to figure out where and why things have grown. Maybe a mock daemon and application (single and multithreaded) would be a good start? There are some example programs in the open_posix_testsuite (see LTP) that might be good for at least getting non-daemon apps that use pthreads that can be used for instrumenting where and why things have changed.
