From f33a947b56e0667c6e1e3384d00ffb1a5b67060e Mon Sep 17 00:00:00 2001 From: Konstantin Belousov Date: Tue, 14 Jul 2009 22:52:46 +0000 Subject: Add new msleep(9) flag PBDY that shall be specified together with PCATCH, to indicate that thread shall not be stopped upon receipt of SIGSTOP until it reaches the kernel->usermode boundary. Also change thread_single(SINGLE_NO_EXIT) to only stop threads at the user boundary unconditionally.
