I have been following this thread for some time. John Bowman 
submitted a patch for 3.01 on Nov 14 that purportedly fixes the 
problem. I don't know what this does on various OS's and am certainly 
not the one to say it is "the" permanent fix, but there was no 
further comment after that. I'd like to see a fix as the present 
situation certainly is not acceptable in the long run. If John's fix 
works for Linux and does so without data loss, then perhaps it should 
be included and compiled in by configuration option for those OS's 
where it is known to solve the problem.
