Yeah, that should be correct.

That's very strange.  I have no idea why this isn't working on Windows.

If you can use a debugger (or print statements, etc.) to watch the
BlockFile::Lock/Unlock calls and the value of BlockFile::mLockCount
while reproducing the bug, that should help figure out what's going
wrong.  This will be simplest if you start with a project of just one
blockfile (e.g. 1 second of "Generate Tone").

It should work like this:

Blockfile():
   mLockCount = 0
~AudacityProject():
   Lock   - mLockCount = 1
OnPaste():
   Lock   - mLockCount = 2
   Unlock - mLockCount = 1
~Blockfile():
   mLockCount == 1
