iSER, today, is going into the trouble of staying in the kernel thread 
context as long as possible, after receiving it's completion upcall.
I was just a pondering - is it really necessary ? in light of  the SRP’s
different approach.

Any way, there isn’t any immediate intention of changing this - there 
are other issues the iSER code is dealing with, right now.

Thanks,
Guy
