will remain blocked for the whole period of strace execution.
* strace no longer resets SIGCHLD handler in tracees to the default action.

that signal to ensure its own termination with the same signal.

NEWS for strace version 4.11

from the personality of strace, fixed decoding of 32-bit personality
syscalls on 64-bit architectures.
