I proposed to add per-image locking a while ago, but apparently this
wasn't too well liked. I'm can't remember why.
There are 2 tricky parts (as far as I can see):
A) plug-in.c needs to take out an image lock when starting a plugin
operation, and release it on normal (or equally importantly)
abnormal plugin termination.
B) what happens when acquiring a lock fail? Do you queue the
operation up on the lock (hard) or do you fail it (easy)?
