fixes #43
Appended mutex to avoid race condition in threaded mode.
Most dangerous part is handling subresources(
subresource_fetch_handler), because every subresources could arrive simultaneously.So I appended mutex lock and unlock.
note: Nginx seems to support Windows environment, but wrapped API's (
ngx_thread_mutex_t) is not exposed to plugin developers. And originally, this module does not support Windows.
