Comment (by jdemeyer):
The same now with `%time` shows that the time increase is mainly in `user`
time, so it's really the `pexpect` code which is causing the slowdown:
pexpect 2.0:
{{{
sage: %time _ = str(gp("2^2^22"))
CPU times: user 184 ms, sys: 4 ms, total: 188 ms
Wall time: 384 ms
}}}
pexpect 4.0.1:
{{{
sage: %time _ = str(gp("2^2^22"))
CPU times: user 203 ms, sys: 7 ms, total: 210 ms
Wall time: 405 ms
}}}
