[New-bugs-announce] [issue27533] release GIL in nt._isdir

[Jeremy Spiegel]

New submission from Jeremy Spiegel:

In Modules/posixmodule.c, the function os__isdir_impl calls GetFileAttributesA/GetFileAttributesW without releasing the GIL. This is problematic since it can result in disk or network I/O, depending on the filesystem.
