Ubuntu: latest wine update breaks rybka

Crafty no longer uses this so for it, the issue has gone away...

Yes I noticed that. The problem was there until last summer, if I remember correctly, probably until version 22.1. Thanks for the explanation. I had already noticed that Rybka uses one new process for every processor, like Crafty used to in the past. Most other engines use only one process and many threads inside it, so they are not affected by this.

They could be I suppose, in that you can use shmget() in a threaded program as well. But since threads already share evereything, by default, doing this has no real benefit...
