I've just backported the code to enable PTRACE_SEIZE which should fix the race conditions related to signal handling of strace'd processes.  My testing indicates that should resolve this issue (the good news).

The bad news, PTRACE_SEIZE doesn't exist in RHEL 5 or RHEL 6 kernels. I'm sorely tempted to close 559580 as WONTFIX given the need for kernel support to make this work properly in RHEL 5/RHEL 6.

Tested with strace-4.8-7.

Switching to VERIFIED.
