Could I run node repair when disable gossip and thrift?

[Yan Chunlu]

I am running 3 nodes and RF=3, cassandra v0.7.4
seems when disablegossip and disablethrift could keep node in pretty low
load. sometimes when the node repair doing "rebuilding sstable", I would
disable gossip and thrift to lower the load. not sure if I could disable
them in the whole procedure. thanks!
