           Summary: create memory efficient ThreadableInputStream
           Product: Commons
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: IO
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: hauser@acm.org


A org.apache.commons.io.input.ThreadableInputStream that extends
java.io.ByteArrayInputStream.

The idea is that for example a large font in itext (22 MB of arialuni.ttf) is
only loaded once into ONE byte[] buf and many threads can have their
ThreadableInputStreams spawned on the same read-only 'buf' without duplicating
that buf in the memory. They just would have each their own set of mark, pos,
count int's to remain thread-safe.

It may be related to DemuxInputStream and javax.mail.internet.SharedInputStream .
