Use the -o intr mount option on FreeBSD (#462)
FUSE file systems normally indicate their interruptibility by returning
ENOSYS to the first FUSE_INTERRUPT operation. But that causes two
problems for file systems that aren't interruptible:
1) A process may block on a signal, even if another thread could've
handled the signal. The kernel must know whether the FUSE thread is
interruptible before deciding which thread should receive a signal.
2) The protocol allows a FUSE daemon to simply ignore FUSE_INTERRUPT
operations. From the kernel's point of view, that is indistinguishable
from a FUSE_INTERRUPT operation arriving after the original operation
had already completed. Thus, the kernel can't interpret an ignored
FUSE_INTERRUPT as an indication that the daemon is non-interruptible.
With the -o nointr mount option, no FUSE_INTERRUPT operations will ever
be sent. Most FUSE file systems should require no modifications to take
advantage of this mount option.
