TWS 865.7 “historical data request pacing violation”

IB implemented new behaviour in their newest TWS 856.7 – after issuing more than 60 backfill requests withing 5 minutes, all subsequent requests fail with Error 162, “historical data request pacing violation”.
Note that 60 requests means as little as backfilling one month back of 1-minute data for 12 symbols only (in one request you can ask for data maximum 5 days long).

For details see: http://www.interactivebrokers.com/cgi-bin/discus/board-auth.pl?file=/2/39717.html

Unfortunatelly this change breaks backward compatiblity and will need to be addressed in next release of IB plugin.
