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
