there is another problem with gnome_config ... if one program reads some
file ... then a second program writes to it and the first program
changes something in the file and syncs as well .. both writes in the same
second .... the changes from the second program are lost ... (since the
first program doesn't notice the changes and dumps the memory into the
file the way it was when it first read it)

maybe one needs to lock files until one syncs the files ... all profiles
that have the written_to flag should be locked I guess ... and everybody
would have to wait ... now we'll have fun with deadlocks ...

the character at a time reading struck me as ineffective yesterday too
but ... oh well ... the rewrite should be better I guess
