+Subject: ksh history corruption
+
+I have had enough of corrupt ksh history so I had a look at the code to
+try to fix it.  The magical code was very magical so I basically deleted
+most of it and made ksh history into a flat text file.  It handles
+multiple ksh instances writing to the same text file with locks just
+like the current ksh does.  I haven't noticed any differences in
+behavior running this.
+
+Code is much simpler and it shaves ~4k of the binary too.
