When reading/writting the same file repeatedly while doing many simultaneous
operations on different files sometimes the former one fails: read(2) returns
-1 and sets errno to EAGAIN. This is because of a difference between the FUSE
kernel implementation in Linux and FreeBSD, and is being worked on. An example
scenario would be playing a song in XMMS, while building many ports, which
could cause XMMS skip the song. Another observed problem is the current
directory not being found, but entering again would work. The details are
described in fuse4bsd (sysutils/fusefs-kmod) documentation (Linux access is
path based while FreeBSD is vnode based, which may be reused)
