non-linear complexity of :reload combined with :module in ghci
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.
(with GHC 7.0.3, Linux x86_64)
