We will see. Nice to hear. I'll wait for your commentaries. A couple of words how this all was tested. The strace test was endless kernel compilation using standard or straced gcc/make (CC="strace -o /dev/null gcc" ) and periodical killing gcc, make or strace. No problems were observed. If there is an idea of a test, which is mostly for threads, I'll be happy to hear it. Thanks! Kirill
