.d Heartbeat uniformity

[stefan]

From Philip Crotwell:

the example heartbeats in at least some param files in the earthworm 7.3 dist are probably poor choices. For example in import_generic.d:

HeartBeatInt? 120 # Heartbeat interval in seconds

and in import_generic.desc tsec: 120 page: 3 mail: 1 Since those are the same, there are very likely to be missed heartbeats. I haven't looked to see if there are other modules with similar issues.
