net/rpc: lose cached Request on EOF

[powerman]

It looks like a (performance) bug at https://github.com/golang/go/blob/master/src/net/rpc/server.go#L578 - I think before req = nil this should be added:

server.freeRequest(req)

The url posted by the OP is relative to master which changes over time and currently points to the wrong line. Here is the url relative to the latest commit when this issue was created:

go/src/net/rpc/server.go

Line 578 in 514eb4a

req = nil

(Sorry I don't have more value to add here right now in the form of actual code; will need to spend more time absorbing this package.)
