Does this program accept multiple requests?

Reading the documentation I understood that multiple chunks could be send in, am I wrong?

{ cat input ; sleep 1 ; echo slept >&2 ; cat input ; } | ./bin/libavoid-server-linux

Yes, it's being used as a background process here: https://github.com/eclipse-elk/elk/blob/master/plugins/org.eclipse.elk.alg.libavoid/src/org/eclipse/elk/alg/libavoid/server/LibavoidServer.java
