           Summary: test_copen fails on Windows XP as tries os.fork()
           Product: Biopython
           Version: 1.43
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Main Distribution
        AssignedTo: biopython-dev at biopython.org
        ReportedBy: biopython-bugzilla at maubp.freeserve.co.uk


I'm using Biopython from CVS (1.43+), fresh install compiled from source using
MSVC 6.0

Output from: python test_copen.py

opening handle
Traceback (most recent call last):
  File "test_copen.py", line 14, in ?
    handle = copen.copen_fn(print_args, *(range(2) + ['a', 'b', 'c']))
  File
"C:\TEMP\biopython_cvs\biopython_all\biopython\build\lib.win32-2.3\Bio\Mu
ltiProc\copen.py", line 66, in copen_fn
    pid = os.fork()
AttributeError: 'module' object has no attribute 'fork'

Michiel has seen a similar problem on Windows using cygwin (hangs rather than
the attribute error), see bug 2361 comment 7 and this mailing list post:
