NVDA fails to start or give feedback if it can't remove a pending addon folder

[nvaccessAuto]

To reproduce:

1. Use Explorer to navigate into a folder containing an addon, for instance:
   C:\Users\Simon\AppData\Roaming\nvda\addons\systrayList
2. Once you're in that folder, remove the addon using the addon manager.
3. When NVDA is restarted, it attempts to remove this folder, which is now locked because windows explorer is also trying to access it.

On my windows 7 x86 machine, instead of popping up a normal error and speaking, it produces a critical error sound, and closes after a few seconds. I haven't been able to figure out whether there is a message box or something else that comes up, because NVDA is my only screen reader. The oddest part, and the part that left me stranded without a screen reader for several minutes, is the fact that even after the folder is once again writable, NVDA still doesn't start. It was necessary to actually delete the folder associated with that addon before it would start. I tested this several times under windows7. I am using Explorer++, and the process actually closed before I attempted to start NVDA again, so there's no way it could still have been accessing the folder.
