directory doesn't exist, on fresh checkout and --jobs >1.

It happens in the case where there is 3 dependencies:
a
a/b/c/d
a/b/c/e

'a' is processed first. Then 'a/b/c/d' and 'a/b/c/e' are fired simultaneously.
If both are not present, both svn checkout tries to mkdir b and b/c and a race
condition occurs between their call for isdir() and mkdir().

This works around the issue by creating the intermediary directories ourself
before calling out svn and managing the error ourself.
