Does ficon/escon not suspend under those conditions? Our device driver infrastructure in the swap path is aware of that problem and is able to do IO without the need for memory (preallocation of FICON channel programs etc.). Same is true for SCSI subsystem. Thus, this deadlock cannot arise with FICON/FCP.
