It's an unfortunate side effect of how permissions work on
Unix-like systems.  When you move folder X from foo to bar,
all that happens is:

 1) foo is changed to no longer point to X
 2) bar is changed to point to X

The only things that are modified are foo and bar.  Files
and directories inside X are never touched, modified, or
even looked at.

Since trashing a folder just involved moving that folder,
it's entirely possible to trash stuff that you don't have
permissions to delete.  It sucks, but recursively scanning
the directory to be trashed can be expensive.  Right now,
trashing is a constant-time operation.
