... where this "not as good" support apparently amounts to "may corrupt your file system when concurrent write access occurs". This, naturally, is expected for MS-DOS-lacking-"SHARE" semantics; with the FreeDOS kernel though, there seems to be some missing functionality even with its "SHARE" loaded! [I just created and ran a particular test on the latest kernel release (build 2041 compiled 2012-02-07) with the latest "SHARE" (2005-09-14) loaded and it reproducibly causes clusters to be lost. I believe that more serious file system corruption is possible as well.] Concurrent file (write) access is often incorrectly conflated with networking, but can in fact occur even on a single-tasking "single user" system that doesn't run anything network-related. (For historical reasons, most typical DOS programs try to avoid accessing files in a way that would expose such problems, of course.)
