Oh! I afraid this situation.

Business logic of application require hold only one copy
of running plug-in per browser instance.

Currently NPAPI based plug-in testing with Firefox, Opera, Chrome,
Safary on MS Windows shown that plug-in share data across
browser pages, so when first JS call to native method
is  not finished in second call we shown MessageBox to user that
plug-in already running and immediately exit from second call
on MessageBox OK user click.

Currently syncronization done this shared memory in process:

enum {ADDON_STOPED, ADDON_RUNNING};
static int addon_running_state = ADDON_STOPED;

But seems must be rewritten with using interprocess synchronization.

As I wrote I can not get situation when plug-in loaded in separate
process (plug-in itself, I don't know if it share address space with
browser).

Which browser/version you recommend to test this issue (when 2
plug-in instances loaded in separate address space)?
