[release-branch.go1.16] syscall: syscall.AllThreadsSyscall signal handling fixes The runtime support for syscall.AllThreadsSyscall() functions had some corner case deadlock issues when signal handling was in use. This was observed in at least 3 build test failures on ppc64 and amd64 architecture CGO_ENABLED=0 builds over the last few months. The fixes involve more controlled handling of signals while the AllThreads mechanism is being executed. Further details are discussed in bug #44193. The all-threads syscall support is new in go1.16, so earlier releases are not affected by this bug.
