dean gaudet 7d95c8f27d [PATCH] fcntl F_SETFL and read-only IS_APPEND files 
There is code in setfl() which attempts to preserve the O_APPEND flag on
IS_APPEND files...  however IS_APPEND files could also be opened O_RDONLY
and in that case setfl() should not require O_APPEND...

coreutils 5.93 tail -f attempts to set O_NONBLOCK even on regular files...
unfortunately if you try this on an append-only log file the result is
this:

fcntl64(3, F_GETFL)                     = 0x8000 (flags O_RDONLY|O_LARGEFILE)
fcntl64(3, F_SETFL, O_RDONLY|O_NONBLOCK|O_LARGEFILE) = -1 EPERM (Operation not permitted)

I offer up the patch below as one way of fixing the problem...  i've tested
it fixes the problem with tail -f but haven't really tested beyond that.

(I also reported the coreutils bug upstream... it shouldn't fail imho...
