In input-output-hk/ouroboros-network#1136 (specifically, https://github.com/input-output-hk/ouroboros-network/pull/1136/commits/4762d321de39419e88926edd9c8ebc2018227ae2) the exception handler for new threads that catches any thrown top-level exceptions is removed. We should instead use setUncaughtExceptionHandler

in the node/proxy, this should probably use the logging/tracing system
for tests, we could install a handler that rethrows such exceptions to the main thread.
