In application code - probably no problem as whatever resources used will be
tracked by the system and freed.

In system code mucho problems possible, since one would not free resources if
one expects to retry - and these resources may not be associated by the system
with the failed unit of work.

ignored.

different logic based on whether the ‘SDWACLUP’ bit is on or off.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
