5317,non-linear complexity of :reload combined with :module in ghci,SimonHengel,,"{{{ghci}}} shows non-linear time complexity for a sequence of
{{{:module}}} and {{{:reload}}} commands, say we do multiple times:


{{{
ghci> :module *Foo
ghci> :reload
}}}

Steps to reproduce:

{{{
$ time for i in {1..10}; do echo -e ':m Prelude\n:r'; done |ghci
$ time for i in {1..99}; do echo -e ':m Prelude\n:r'; done |ghci
}}}

On my system the first run uses 1 second of CPU time, the second 39
seconds.
