Limit's of WMIC: 2nd Post

The WMIC command line appears to have some serious scalability limits:

e.g. WMIC Datafile (yes everything)
will fail with error:0x80020009 Error Dispatch Facility.

e.g. WMIC Datafile "where Extension='txt'" will work up to about 30 text
files.
After that
error:0x80020009 Error Dispatch Facility

Why do these errors and limits occur? And how can I get around them in WMIC
(I am specifically doing this in WMIC as I am piping to another Command line
program. I can do this in .NET just fine, but this time I need WMIC)

Thanks
