[vbox-dev] Python mmap issue with shared folders

I have encountered a possible problem with python's memory mapping for
files in shared folders. My testing system is a Windows 7 x64 host
with a Ubuntu 10.04 x86 guest. When opening a file as a mmap by doing
with open(fname, "r+b") as f:
# memory-map the file, size 0 means whole file
fmap = mmap.mmap(f.fileno(), 0)
I get an error message:
error: [Errno 22] Invalid argument
This is a minor issue - copying the file from the shared folder into
the virtual machine's local storage makes the issue disappear.
Is this worth filing a bug report, or not?
