A VFS plugin may only use very limited LibC functionality. In many
aspects this constellation could be compared to the execution of an
application program inside the kernel on Linux. So it's tricky to get
right and stable. I suggest to look for other options if pthreads
and/or blocking file-system operations come into play.

Beside that you may look into a prior discussion on this list [1] and
the FUSE genode-world issue [2] (esp. Norman's reply [3]) for
inspiration.
