Answering my own question, the distribution of the current logfile name
could be done trough a file handle. So the only thing remaining in
shared mem would be the "reopen logfile" flag, which seems
nonproblematic. In case of garbled sharedmem, a backend would reopen the
logfile, which does no harm at all, or continue writing the outdated
logfile which would be annoying but not harmful either.
Acceptable?
