From bddde5860ffb8a78587854cc8e3e914bd69269ca Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sun, 22 Jan 2017 10:24:51 +0100 Subject: remove PID caching Follow GNU C Library from c579f48edba88380635ab98cb612030e3ed8691e and remove the PID caching. These simplifies the architecture specific assembly code. The run of the test suite found no regressions, it even solves some of the test failures for x86/x86_64/sparc.
