More specifically, this is how the libguestfs API works:
Main thread Other thread ----------------------------- ---------------------
guestfs_mount_local (g, "/mntpoint");
calls: fuse_mount fuse_chan_fd fuse_new
fork () or pthread_create () --creates--> Start to access the /mntpoint; blocks until main thread calls fuse_loop
I don't know how the blocking thread is implemented? by fuse self or libguestfs?
The system calls block until FUSE is ready to handle them, so in other words, FUSE/kernel handles it.
