Showstopper and regression against 5.0.24.

Previously, we ignored seek() errors (see Bug#22828) and let seek()s
against pipes fail.  Now, since we check that a seek didn't fail,
and return without reading, this bug popped up.

This restores the behavior for file-ish objects that could never be 
seek()ed.

Under high load it was possible that memory mapping was started on a table
while other threads were working with the table.

I fixed the start of memory mapping so that it is done at the first table
open or when the requesting thread is using the table exclusively only.
