The button links send "GET " commands, which REQUIRE loading a page of some kind.. but you could "GET /dev/null" for really short ouput. Maybe I'll redirect "?button=xxxx" to /dev/null in v129, just for a trial.

Also, table-based CRC32 turns out to take 1/10 the CPU usage (I measured it) of the non-table version used in v128. So, I guess I'll waste another KB on a CRC table..

Cheers
