Hi!

I was expressing some group (in fact, libgap.SuzukiGroup(8)) as a permutation
group (via regular permutation action) and took the string representation of
that permutation group. Reason: GAP doesn't know how to pickle individual
objects, but GAP can reconstruct a group from its string representation.

Problem: While the pexpect GAP interface can evaluate a string of that
length, libgap tells me:
  python2: libgap.c:184: libgap_get_input: Assertion
  `strlen(libGAP_stdin_buffer) < length' failed.
and then raises a value error.

What to do? In the pexpect interfaces, evaluation of large strings
typically works via temporary files. Would it be a good idea to
implement the same for libgap.eval(...), too?

Best regards,
Simon
