The problem is that acme is basically a single operating system thread, and that operating system thread is trying to look in /mnt/acme. To serve that request, the kernel has posted a FUSE message to acme to handle, which acme will get around to just as soon as the system call in /mnt/acme finishes. Deadlock. This is not a problem on Plan 9 because acme does not put itself in its own name space. On Linux, where there is just one big name space, more care is necessary (and not implemented). Russ
