[fixed] There's something terribly broken in saving and/or loading SavedVariables

[merlight]

I took a chunk of data from my saved vars and put it in an add-on that throws several copies of that data into saved vars. Here's the add-on: svFailTest.7z

Here are the steps I used to get corrupted saved vars:

1. disable all other add-ons, enable svFailTest (no saved vars file yet)
2. login
3. /svfail
4. /reloadui
5. check SavedVariables/svFailTest.lua: mine has 118715 lines / 21802807 bytes
6. /reloadui
7. check SavedVariables/svFailTest.lua:
   • if empty (this is an error, too), go to step 3.
   • otherwise look for the string "svFailTestSV"
     for me the corrupted file has 118715 lines / 21595305 bytes (~200k less), and the corruption starts at line 115950
