Without getting too commercial here, your best bet on this issues is to
check with the vendor. Several vendors do provide this facility: a task
about to block on an I/O operation relinquished the processor so another
task caN be scheduled. This is actually fairly trivial to implement
when an Ada task directly issues the I/O operation request. Where it
gets more interesting is when an Ada task calls interfaced code
(EG third party software) which issues an I/O call which will block.
