The connection between stunnel and rsync is just a normal socket connection.
I've also ran an stunnel server process on a different machine that then
connects to rsync on the server machine in an attempt to isolate any strangeness from
local connections. I get the same results of a hung generator process.
for clarity, the above test looks like this:
[rsync client]<-localhost->[stunnel process on client]<--local lan-->[stunnel process on server 1]<-internet->[rsync process on server 2]
Any suggestions on how to find out more of what's going on?
