New submission from Laurens <3.14159265...@xs4all.nl>:
file.tell() has become extremely slow in version 3.2, both rc1 and rc2. This

Correction: the problem also exists in version 3.1. I created a benchmark
program an ran it on my machine (iMac, snow leopard 10.6), with the following
results:

First of all, thanks to all for your cooperation, it is very much appreciated.
I made some minor changes to the benchmark program. Conclusions are:

All,
thanks for your help. Opening the file in binary mode worked immediately in the
toy program (that is, the benchmark code I sent you). (Antoine, thanks for the
hint.) In my real world program, I solved the problem by reading a lin

To be more precise, consider code

\tx=0 # 7 spaces + one tab
return x # 8 spaces
In cpython, both indentation levels are 8 and no indentation error is reported
(this is the case where both tab size and alt tab size are equal)

Since the text and tail notions seem tightly coupled, I would vote for a more

The totsstring(..., method='text') is not suitable for the inner text because
it adds the tail of the top element.
A proper implementation would be
