Are PerlIO_flush calls required for DBD debugging?

[Martin J. Evans]

I'm trying to debug a DBD::ODBC problem and the code is full of:

if (ODBC_TRACE_LEVEL(imp_sth) >= 2) {
    PerlIO_printf(DBIc_LOGPIO(imp_dbh), "something");
    PerlIO_flush(DBIc_LOGPIO(imp_dbh));
}

Are all those PerlIO_flush calls required? I'm finding it difficult to
see the wood for the trees and I notice other DBDs don't use
PerlIO_flush. Can they be removed?
