This is a case that I've specifically tested for in the past, so I'm a bit
surprised to see this bug report. sendfile(2) holds a vnode reference to the
file (via the open file descriptor), which should prevent bad things from
happening when the file is unlinked (the actual deletion is defered until
all internal references have been dropped). Is it possible that there is more
involved than just deleting the file? Can you provide a traceback?
