[Halld-offline] non-repeatability in reading events into JANA

Hello Simon, Thomas,

I just tried to reproduce your observation of non-repeatability of
hits-level objects in jana, but I only get perfect repetitions. This is
what I did.

$ hd_dump -p -PEVENTS_TO_KEEP=20000
$PSSKIMS/Run041343/hd_rawdata_041343_000.ps.evio >run_041343_000.ps.list
$ hd_dump -p -PEVENTS_TO_KEEP=20000
$PSSKIMS/Run041343/hd_rawdata_041343_000.ps.evio >run_041343_000.ps.listb
$ vimdiff run_041343_000.ps.list*

I get a few differences in the startup messages, but as soon as regular
event hits dumps begin, there are no further differences, out to 20,000
events. Should I check further?
