I honestly don't remember the circumstances that caused me
to add this -- it's been sitting in my sandbox for a while.
Thought it would be better to offer it up than to throw it
away...



Wouldn't a message like this be symptomatic of failure in GDB's executable date detection code, or in the executable production bits?


If I understand it, we get that message precisely when
gdb's executable date detection code works as intended.
It discovers that the executable's modification date has
changed, and therefore re-reads the symbols.

But when would that happen while running the testsuite? I would expect that the executable is left alone between run commands - if GDB thinks it needs to re-read symbols between run commands on the same executable, that seems like a GDB bug and a performance loss to boot.
