On linux (and possibly other related unices), we can use
getrlimit(RLIMIT_STACK)

The stack size of the main thread is still estimated in std::rt, so I think the issue remains relevant.

reopening: the code in question is still just guessing, AFAICT, and appears to be triggering an overflow (or underflow) panic on the branch with arithmetic overflow checking: http://buildbot.rust-lang.org/builders/auto-linux-32-opt/builds/3910/steps/test/logs/stdio
