[vbox-dev] Shared Folders broken in latest 4.0.51

[Alexey Eromenko]

Hi All !

Host: Windows 7 x64 + VBox 4.0.51 r71902
Guests: Windows XP and Win 7 (all) + VBox Additions 4.0.0

Using any VBox 4.0.x have good experience, but after upgrading host to
4.0.51 I suddenly having read errors.
Many files stopped being read, and even worse: python stopped working.
(I did not upgrade GA to 4.0.51)

Steps to reproduce:
1. Run python program (I used GNS3) from shared folders
2. It will work first time (and create *.pyc files)

Problem:
Attempt to run it again will fail (fail from *.pyc fails)

Workaround:
Remove all the *.pyc files and re-run from source. This will succeed.
Degrading host to 4.0.x solves this.

In addition a lot of setup exes now fail to run from SF.
