at some level it must be known that file handles are a 'scarce'
resource, so at some level you could do something like:
try {
file = IO.openFile(fileName);
} catch (noFileHandlesLeft e) {
Runtime.doGarbageCollection();
Runtime.doFinalisation();
file = IO.openFile(fileName);
}
i see no reason why this can't be done inside IO.openFile, thus
keeping the scope of the knowledge (that file handles are scarce)
within the package.
