For the record, I can reproduce this problem intermittently on
OpenBSD:

    fire $ uname -a
    OpenBSD fire.0--0.org 3.6 GENERIC#304 sparc64
    fire $ cat INBOX | wc -c
     4106962 
    fire $ (ssh localhost sleep 120& sleep 3; cat INBOX) | wc -c 
     4106962 
    fire $ (ssh localhost sleep 120& sleep 3; cat INBOX) | wc -c
    cat: stdout: Resource temporarily unavailable
