possible 100% java implentation for chdir

I realize chdir is not a high priority and there have been postings

saying that a 100% java implementation is not possible--however, I

(perhaps naively) suggest it is possible and provide source (attached). 

 

Would this be of interest to give jython a chdir?

Sample jython session (assumes presence of dir C:\temp):

 

Jython 2.1 on java1.3.1_01 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path.append("C:\\temp")
>>> import CurrentDir as CD
>>> cDir = CD("C:\\temp")
>>> cDir.mkdir("aDirectory")
1
>>> cDir.cd("aDirectory")
>>> cDir.mkdir("test")
1
>>> cDir.cd("test")
>>> from java.io import File
>>> File(cDir.toFile(), "dummy.txt").createNewFile()
1
>>> cDir.list()
array(['dummy.txt'], java.lang.String)
>>> cDir.delete("dummy.txt")
1
>>> cDir.list()
array([], java.lang.String)
>>> cDir.renameTo("test_renamed")
1
>>> cDir.cd("..")
>>> cDir.list()
array(['test_renamed'], java.lang.String)
>>> cDir.delete("test_renamed")
1
>>> cDir.cd("..")
>>> cDir.delete("aDirectory")
1
