It is not fifo or character but Unix domain socket. But the same problem
applies (pointed out to me by Christian Plattner author of Ganymed).

JRuby has solved this problem by using JNA to implement domain sockets. And
the junixsocket uses JNI and its binary jars come with compiled libraries
for Linux 32/64, Mac 32/64. Getting this more complete to support more
platforms shouldn't be too difficult.

See also https://bugs.eclipse.org/bugs/show_bug.cgi?id=179924 discussing the
same problem for ssh-agent.
