Andrew G. Morgan	025f28ca4f	Avoid thread churn deadlock with PSX rewrite. ... This bug, reported by David Runge, identifies another regression vs. libpsx-2.71: https://bugzilla.kernel.org/show_bug.cgi?id=219687 A regression of the LWP threading support reintroduced an old bug in the libpsx-2.72 rewrite, specifically this bug: https://github.com/golang/go/issues/42494 This present change includes x86_64, i386 and arm* (32-bit and 64-bit) support. I've tested each of these with debian OSes, some running via QEMU. Before releasing 2.74, I plan to extend the testing to all of the targets supported by Debian (see https://wiki.debian.org/DebianInstaller/Qemu). Signed-off-by: Andrew G.

Andrew G. Morgan	481ca7b508	Demonstrate why libpsx is important for multithreaded C code. ... I've heard a number of folk ask why one might need libpsx for anything other than Go program linking, so this demonstrates the class of exploit that is possible when libcap is linked with -lpthread and not -lpsx.
