[issue43390] Set the SA_ONSTACK in PyOS_setsig to play well with other VMs like Golang

Gregory P. Smith added the comment: I expect zero fallout from this given the semantics. SA_ONSTACK really appears to be something that should've been the POSIX default since it was introduced as a feature in ~BSD4.2 in the early 80s. But it never was. It'll be good to have in the beta rel

[issue43390] Set the SA_ONSTACK in PyOS_setsig to play well with other VMs like Golang

New submission from Gregory P. Smith : PyOS_setsig currently sets the struct sigaction context.sa_flags = 0 before calling sigaction. Other virtual machines such as Golang depend on signals using SA_ONSTACK such that signal handlers use a specially allocated stack that runtime sets up for re
