pub fn install_exit_handler()Expand description
Install orderly shutdown hooks for SpiderMonkey.
No-op at init time. Tests should call shutdown_thread_sm() at the end
of each test function (before returning) to properly clean up the
SpiderMonkey Runtime and Engine. Without this, C++ TLS destructors
(MutexImpl::~MutexImpl) will SIGSEGV on thread exit.
This function is kept for API compatibility with existing test files.
