Subject: fix: don't use select as wait function if possible
X-Git-Tag: 3.1.9~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b347bfe483c9f5661e0611229378c06518d952c7;p=thirdparty%2Fpsycopg.git

fix: don't use select as wait function if possible

select is marginally faster than others, but has the limitation of not
allowing FD > 1024, so it is not a good default.

If people need performance, they will use wait_c anyway, which is based
on poll, and doesn't have the limitation.
