Hey Guys,
Sorry to jump in late here but could you give a couple more sentences of
clarification of what this patch intends to accomplish?
Is this simply a performance gain by allowing the users of
google::GetStackTrace() to block signals once (and maybe lock a mutex) at a
higher level of libunwind? Or does this help ensure correctness and more
complete stack traces?
I'm wondering if we should turn this option on in our multithreaded servers
that take a lot of traces (sampling some various activities).
