From 05098a9315819621405eb662baddeec624127d7a Mon Sep 17 00:00:00 2001 From: Riku Voipio Date: Fri, 4 Mar 2011 15:27:29 +0200 Subject: [v2] linux-user: bigger default stack PTHREAD_STACK_MIN (16KB) is somewhat inadequate for a new stack for new QEMU threads. Set new limit to 256K which should be enough, yet doesn't increase memory pressure significantly.
