[Isolate-interest] Why are StreamBindings only for files and sockets?

[Curt Cox]

Hi,

I'm curious why javax.isolate.StreamBindings streams are limited to either
files or sockets, while java.lang.System streams have no such limitation.
Even if something in the implementation forces this limitation, wouldn't it
be better to use PrintStream/InputStream and throw an
IllegalArgumentException when appropriate?
