as i've mentioned in the previous mail, 2.5.35+ kernels have a very fast SIGSTOP/SIGCONT implementation, which change was done as part of this project - a few orders faster than throwing/catching SIGUSR1 to every single thread for example.
so right now we first need to get some results back about how big the GC problem is with the new SIGSTOP/SIGCONT implementation. If it's still not fast enough then we still have a number of options.
