[ECOS] file deletion / unlink problem

[David Brennan]

Because the filesystem is buffered, the delete does not occur unless you 
unmount the file system or an FSSYNC. FSSYNC is something I added a 
while back specifically for this. (There is probably some discussion on 
the Mailing list back in October of 2004, starting with 
http://sourceware.org/ml/ecos-patches/2004-10/msg00074.html). You call 
it using a setinfo call with a FS_INFO_SYNC operation.
