[issue3873] Unpickling is really slow

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

Note about my patch: the buffer should be truncated after
PyBytes_Concat(&self->buffer.pybytes, data) to avoid very long buffer.
Something like: self->buffer.pybytes += data; self->buffer.pybytes =
self->buffer.pybytes[index:]; self->buffer.index=0;
