New submission from Diego Queiroz <queiroz.diego at gmail.com>:
There is a problem with dir_util cache (defined by "_path_created" global variable).
It appears to be useful but it isn't, just repeat these steps to understand the problem I'm facing:
1) Use mkpath to create any path (eg. /home/user/a/b/c)
2) Open the terminal and manually delete the directory "/home/user/a" and its contents
3) Try to create "/home/user/a/b/c" again using mkpath
mkpath should create the folder tree again.
Nothing, mkpath "thinks" the folder already exists because its creation was cached. Moreover, if you try to create one more folder level (eg. /home/user/a/b/c/d) it raises an exception because it thinks that part of the tree was already created and fails to create the last folder.
I'm working with parallel applications that deal with files asynchronously, this problem gave me a headache.
Anyway, the solution is easy: remove the cache.
