You may want to look into what the domain module[1] has to offer. To
quote the preface:
"Domains provide a way to handle multiple different IO operations as a
single group. If any of the event emitters or callbacks registered to
a domain emit an error event, or throw an error, then the domain
object will be notified, rather than losing the context of the error
in the process.on('uncaughtException') handler, or causing the program
to exit with an error code."
