There is an assuption in the lib/libc/gen/*dir* code that at some point in the future that kernel/user page trades will at some point be possible. It turns out the dirent.h defines the system wide limit on DIRBLKSIZ to 1024. For anyone who's curious, 1024 is smaller than a page. Probably this ought to be increased to the page size (I'd hope using an include plus a #define DIRBLKSIZ DEFAULTPAGESIZE or something similar). So currently, the practical limit is 1024.
