    Another part of the fix for bug 6651 - smbd SIGSEGV when breaking oplocks.
    SA_INFO_QUEUE_COUNT *MUST* be a power of 2, in order for the ring buffer
    wrap to work correctly at the 32 bit boundary. Thanks to Petr
    Vandrovec <petr@vandrovec.name> for this.

changed the SA_INFO_QUEUE_COUNT from 100 down to 64.

I think we should change TEVENT_SA_INFO_QUEUE_COUNT to 128 or even more,
and add a function to ask for this limit.

This is fixed at least in the latest 4.2.3
