Comment:
Looking better now:
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 upstream:
{{{
sage: %time _ = str(gp("2^2^22"))
CPU times: user 308 ms, sys: 9 ms, total: 317 ms
Wall time: 571 ms
}}}
pexpect 4.0.1 + Sage patches:
{{{
sage: %time _ = str(gp("2^2^22"))
CPU times: user 26 ms, sys: 2 ms, total: 28 ms
Wall time: 231 ms
}}}
