Thomas,
You should be using __lock_init_recursive to initialize the locks rather than zeroing them out.
The code in __sbprintf should probably be closing the lock after the call to VFPRINTF as well.

This patch adds support for thread safe stdio for Cygwin.
Cygwin uses dynamic mutexes for locking, therefore it is necessary to:
1. Initialize FILE pointers _lock properly. 2. Destroy the lock when it is no longer needed.

Thomas
