edts_code:refresh() causes mnesia to crash

[josephDunne]

Any call to edts_code:refresh() with a system running mnesia causes a crash when mnesia_late_loader module is purged and reloaded:

=SUPERVISOR REPORT==== 12-Apr-2013::23:25:16 ===
     Supervisor: {local,mnesia_kernel_sup}
     Context:    child_terminated
     Reason:     killed
     Offender:   [{pid,<0.207.0>},
                  {name,mnesia_late_loader},
                  {mfargs,{mnesia_late_loader,start,[]}},
                  {restart_type,permanent},
                  {shutdown,3000},
                  {child_type,worker}]

which brings down the VM. We need a way to only reload modules specific to the project. Unfortunately the mnesia directory is not marked as sticky (http://www.erlang.org/doc/man/code.html#is_sticky-1) so the code is purged resulting in the above error

Yeah, that's not so good :) Perhaps a better solution would be to only reload modules that have actually been changed. I would like edts to work for otp-development as well as other projects.

Try it now.

Awesome thanks that works. I'll try recreate this issue on an OTP build (our project structure is a little complicated) and let you know.

Thanks for the awesome project!
