Running tests twice on windows leads to failures

I narrowed it down: it suffices to run only testcase u0038 to get the failure in st_web_18002_main_no_wf.

in testcase u0038_test_wdmapping a descriptor is created and added to the .sgcloset-test descriptors:
"r1" : { "repo_id" : "blah", "hello" : "world", "hola" : "mundo" }

I guess that descriptor is responsible for the server failure.

Here's a diff for the fix that solved the problem for me:
