One data point on my hang -- I increased /proc/sys/net/core/wmem_{max,default} from 64k to 256k, and then increased /proc/sys/net/ipv5/tcp_wmem from "4096 16384 131072" to "16384 65536 262144", and the hangs seem to have either stopped or (more likely) drastically reduced in frequency. I was able to rsync a couple GB without stalling. I can perform more tests, if anyone has anything in particular that they'd like to see.
