[mkgmap-dev] Problem with --index and 812KB _mdr.img files &"warning using default sort"

Thu Mar 17 09:30:23 GMT 2011

A trick I use to deal with this problem is to generate the files with a .embryo 
extension and once I know the file has been successfully written out and 
closed I perform a rename (which is atomic) to get rid of the .embryo. The 
next time the application is run, it can cleanup any .embryo files on startup 
(or just ignore and overwrite them). It's also possible to add uncaught exception 
handlers and shutdown hooks to try to clean up the incomplete files, but 
this can be tricky to get right, and it's often it's better to leave them 
there for diagnostic purposes anyway.
