[KinoSearch] cleaning up after a failed update..

[Dan]

So after aborting a index updating session... the readers are running
just fine but all new writers get a

Can't open 'seg_5.ds': File exists at
../c_src/KinoSearch/Store/FSFolder.c:55 kino_FSFolder_open_outstream
	 at build_index.pl line 12

So i have played around a bit  and removed all the seg_5.* files and
things seem to correct itself.
I'm sure that is screwing up something...

How should it act after a failure of a writer?
How should i recover from this type of failure?
