> Some of the {{libprocess}} tests will allocate a {{Process}} on the stack and then {{wait}} on that at the end of the test. If the test fails before the process it waited on, however, {{gtest}} returns from the test function, causing the stack variable to be deallocated. However, there is still a pointer to in the {{libprocess}} {{ProcessManager}}, so when {{libprocess}} finalizes, we end up throwing exceptions because the stack variable is trashed.
