increase default thread stack/guard size
stack size default is increased from 80k to 128k. this coincides with Linux's hard-coded default stack for the main thread (128k is initially committed; growth beyond that up to ulimit is contingent on additional allocation succeeding) and GNU ld's default PT_GNU_STACK size for FDPIC, at least on sh. guard size default is increased from 4k to 8k to reduce the risk of guard page jumping on overflow, since use of just over 4k of stack is common (PATH_MAX buffers, etc.).
