BEREC (the European head regulator) is a bit cryptic about this. Quote from the report:

"BEREC asked operators if they have updated their wholesale roaming agreements to include clauses to prevent permanent roaming. Some operators answered that there were cases of permanent roaming traffic that are not easy to monitor or identify and other roaming providers have not updated their agreements yet because they are studying measures to implement. However, other roaming providers have pointed out that they have included general clauses to suspend wholesale services or to terminate the agreement in case of permanent roaming is detected based on Article 3 of the Roaming Regulation."

In short, some providers do, others don't and the whole monitoring is hard and costly to implement. For this new German wiki I'm running some very cheap offers right now already more than 6 months on permanent roaming. Strict measures with a 4-months time-out have been reported only by Austrian, Polish and Romanian providers and Three UK so far.
