Imports are not necessarily contained in the .idata section. Also base
relocations can touch just about every code page, so you'd need to
unprotect everything. Probably easier to only set up the right
permissions after all imports and relocations have been done.

Also note that it is allowed for an app to write to the resource
section, even though it is marked read-only. NT sets up an exception
handler to unprotect it when necessary; this is supposed to help in
finding bugs. So you probably have to do the same thing.
