+// removeCertificate.
+
+// It loads a copy of the test certificate database,
+// removes all certificates and keys, then imports the certificates and keys
+// again.  Then it runs a secure server, using the user certificate (a
+// certificate with private key), and starts client processes that use
+// addCertificate to trust the certificate that signed the server's certificate.
+// The clients then test that they can successfully connect to the server.

I think we should open a bug on improving this. This could lead to issues with
building right after running tests as dart.exe will be locked for a period.

Using the dart.exe used for the testrunner could fix that.
