SIGHUP managed proxies when logs reopened

We use SIGHUP to cause Tor to reopen its logs after a rotation, but currently this SIGHUP is not passed along to a managed proxy (ie obfsproxy). The only way to automatically tell obfsproxy to reopen logs without finding its process and sending a SIGHUP manually is to do a full tor restart, which will kill and restart the managed proxy as well. Perhaps all SIGHUPs to Tor should just be passed along to any (unchanged argument) managed proxies?
