Robert Watson ae11a989e6 When writing trailers in sendfile(2), don't call kern_writev() ... while holding the socket buffer lock. These leads to an immediate panic due to recursing the socket buffer lock. This bug was introduced in uipc_syscalls.c:1.240, but masked by another bug until that was fixed in uipc_syscalls.c:1.269. Note that the current fix isn't perfect, but better than panicking: normally we guarantee that simultaneous invocations of a system call to write on a stream socket won't be interlaced, which is ensured by use of the socket buffer sleep lock. This is guaranteed for the sendfile headers, but not trailers. In practice, this is likely not a problem, but should be fixed.
