Change in convert-ly with 2.15.14?

[Nick Payne]

I use jEdit with Lilypondtool to edit ly source files. I recently 
installed LP 2.15.14, and now, when I open an ly file in jEdit and run 
convert-ly from the Lilypondtool menu or toolbar, I get two error 
dialogs from jEdit. The first is titled "I/O Error" and says "Each 
buffer can only execute one I/O operation at a time. Please wait until 
the current operation finishes before starting another one". Behind that 
is another dialog titled "Files changed on disk", and says 
"Automatically reloaded: ", followed by the name of the file.

I haven't seen these messages before when running previous versions of 
convert-ly with the same editing setup, and I have been using jEdit and 
Lilypondtool for a considerable time without any version upgrade to 
either. jEdit 4.4.1 and Lilypondtool 2.12.932 on Ubuntu amd64. In the 
jEdit global options I have it set to automatically reload open files if 
they are changed on disk, but this is how I have always had it set, and 
these error messages have only been appearing since installing LP 2.15.14.
