 Given a {{{.ghci}}} file in the current directory, when I start {{{ghci}}}
 it loads that file. However, {{{ghci}}} keeps that file open and locked
 while running. As a result, any attempts to edit the file give an error
 from my text editor of "Encountered a sharing violation while accessing
 .ghci".

 The solution would be for {{{ghci}}} to strictly read the {{{.ghci}}} file
 before it starts, rather than leaving the handle to the file open.

 Reported against 7, but it's been this way for a while. Could well be
 Windows specific.
