Hi Noah, Thank you for the push. Now I don't have SIGSEGV anymore. By the way, is there any way to move the ceph_is_mounted() function into the java library's code instead of putting it in the main Ceph's code? > The basic idea was that threads in Java did not map 1:1 with kernel > threads (think co-routines), which would break a lot of stuff, > especially futex.

And I'm using Java 6, so threads should be real threads. My guess is that it's related to some internal locking mechanism.
