" Inserts 2 million lines with consecutive integers starting from 1
" (essentially, the output of GNU's seq 1 2000000), writes them to Xtest
" and writes its cksum to test.out.
"
" We need 2 million lines to trigger a call to mf_hash_grow().  If it would mess
" up the lines the checksum would differ.
"
" cksum is part of POSIX and so should be available on most Unixes.
" If it isn't available then the test will be skipped.
