Version 3.4.2
More work on ES-Harmony proxies. Still hidden behind a flag.
Fixed some crash bugs and improved performance.
Fixed building with gdb debugging support.
Do not install SIGPROF handler until it is needed.
Added DateTimeFormat to i18n API.
Fixed compilation on OpenBSD.
Take the ulimit into account when sizing the heap. OpenBSD users
may still have to increase the default ulimit to run heavy pages in
the browser.
