I discovered a possible easier way: perfused shares a socketpair with
the parent (that is, the filesystem), and it uses send/recv to talk with
it. I just noticed I used MSG_NOSIGNAL here. As I understand, if I
remove MSG_NOSIGNAL, I should get a SIGPIPE when parent dies. 

Unfortunately I do not get any signal. I understand that is wrong, and I
suspect it may be a SOCK_SEQPACKET bug.
