#4407: magma -- painful scalability issue with parser and interface

{{{
sage: a = magma('"%s"'%('n'*1000000))
[[works instantly, uses almost no memeory]]
sage: magma.GetMemoryUsage()
15728664
}}}
Now do the same, but with just 10 times as much input (be ready to kill
magma processes). This will uses several GIGABYTES.
{{{
sage: a = magma('"%s"'%('n'*10000000))
^C^Z
}}}
This is probably some major magma parser issue. We should nail down the
bound, then either:
(1) find some clever way to program around it,
(2) report it as a bug to Allan Steel,
(3) give an error message instead of blowing up people's computers
