[...] I was interested to hear the ever-more-urgent pleas from a
Cirrus flight of four to speed things up because their engines were
over-heating as they sat idling in line.

Didn't hear anything like that from any of the dozens of other aircraft
waiting to go. [...]

Maybe those others don't have engine monitors to make the worsening
situation obvious. A tightly-cowled big-bore engine will be stressed
if left to idle too long. First hand experience: I tried not to whine
about it on air beyond offering to depart VFR, but a 45-minute
take-off wait at KTEB last week made my IO-540s very unhappy.
