Move original t5375 to pending

Needs to be replaced by something that doesn't use the parallel
collections, I attempted to do so in
b9ba16e but the result caused
deadlocks, don't have time to investigate right now.

+/** Hello fellow compiler developer.
+    if you are wondering why does test suite hang on this test
+    then it's likely that the lambda inside map has been compiled into static method
+    unfotrunatelly, as it is executed inside static object initializer,
+    it is executed inside class-loader, in a synchronized block that is not source defined.
+    
+    If the lambda will be static Test$#foo, calling it through a different thread would require grabbing the
+    lock inside classloader. Unlike if it not static and is called through This(Test).foo, no lock is grabbed.

+  catch {
+    case ex: RuntimeException => println("Runtime exception")
