PR jupyter-server#279 introduced some fixes to address file descriptor leaks - one of which was to shutdown the communication port. Since the kernel launcher listening on the other side may have already terminated, the shutdown method could throw an exception. This change catches, logs, then ignores such exceptions. While looking into other leaks (in this case memory), it was discovered that the process proxy instance was being leaked across kernel cycles. This change addresses that particular leak. Note: Other PRs have also been submitted to address leaks in `jupyter_client` and `notebook`. These are: [PR 360 - Fix memory leak of kernel Popen object](jupyter/jupyter_client#360) [PR 361 - Fix memory leak of IOLoopKernelManager object](jupyter/jupyter_client#361) [PR 3424 - Fix memory leak of iopub object in activity monitoring](jupyter/notebook#3424)
