It's not impossible, especially considering you're looking at WAT-WAT
hydrogen bonds. There will be one line in the lifetime entry for each
hydrogen bond, and even with only 1000 waters that's like close to 2
million possible donor-acceptor pairs. However, what is unusual is
that you're able to write out hbavg.dat but not hbwater-lifetime.dat -
they should have the same number of lines. Are you sure the file
that's gigantic isn't hbseries.gnu? I could easily see the time series
file getting out of control.
