apt: sometimes can't remove .dll files

[maphew]

D:\o4w> apt remove msvcrt
removing msvcrt 1.0.1-2
Traceback (most recent call last):
  File "b:\o4w\apt\apt.py", line 787, in <module>
    __main__.__dict__[command] ()
  File "b:\o4w\apt\apt.py", line 633, in remove
    do_uninstall ()
  File "b:\o4w\apt\apt.py", line 613, in do_uninstall
    if os.remove (file):
WindowsError: [Error 5] Access is denied: 'D:/o4w\\bin/msvcp71.dll'

deleting the file manually and running apt remove again is a successful workaround

In this particular instance I was editing apt.py with the Leo Editor the same time as testing apt remove. Leo was using msvcp71.dll so of course it couldn't be deleted. Moral of the story: close other apps using anything in the o4w tree before attempting to uninstall.

On the bright side, it appears apt install and apt remove can be run successively until it finally gets everything done.
