--- Comment #12 from Kirill Smelkov kirr@landau.phys.spbu.ru 2011-05-05 03:04:21 CDT --- Created an attachment (id=34485) --> (http://bugs.winehq.org/attachment.cgi?id=34485) 0001-bash-Don-t-load-user32.dll-for-every-shell-process.patch
Also bash.exe was pulling user32.dll in for clipboard's paste to work in readline. Delay loading user32.dll for bash.exe made shell scripts almost 2x faster under wine.
