selftest on win32

[Alexander Belchenko]

Because I'm running selftest on my Windows XP for checking John's patch,
I think I could share some results. There still many failures due locking problems,
but also I've noticed 2 new (for me) problems:

ERROR:
branch_implementations.test_parent.TestParent.test_win32_set_parent_on_another_drive(BzrBranchFormat5)
    'BzrBranch6' object has no attribute 'abspath'

ERROR:
branch_implementations.test_parent.TestParent.test_win32_set_parent_on_another_drive(BzrBranchFormat7)
    'BzrBranch6' object has no attribute 'abspath'

ERROR:
branch_implementations.test_parent.TestParent.test_win32_set_parent_on_another_drive(BzrBranchFormat6)
    'BzrBranch6' object has no attribute 'abspath'

ERROR:
branch_implementations.test_parent.TestParent.test_win32_set_parent_on_another_drive(BranchReferenceFormat)
    'BzrBranch6' object has no attribute 'abspath'

ERROR:
branch_implementations.test_parent.TestParent.test_win32_set_parent_on_another_drive(BzrBranchFormat4)
    'BzrBranch6' object has no attribute 'abspath'

If this attribute was removed recently this failure means that
test_win32_set_parent_on_another_drive should be simply updated? This error

Second problem much harder: selftest seems to hang (no disk/processor activity) on

[8090/14144 in 36m57s, 33 err, 18 fail, 3 missing]
test_http.TestBadProtocolServer.test_http_get(urllib,HTTP/1.1)

So I've killed it.
