XS BOOT: and threading

If XS code provides a code in BOOT: does perl make any guarantees that the
bootstrap code on a module is locked so that only one thread can ever enter
it?

I'm assuming that if no explicit lock is made then 2 threads attempting to
use a Dynaloaded module can both end up calling the BOOT code. Am I right?

Basically I'm thinking of initialising a static SV * in the BOOT: section
and wonder if I need to do something to be threadsafe.

[The SV is newSVpvn("none",4) and never needs to change]

Dynaloader supports unload now doesn't it? Is there un-BOOT code to free these
sort of things?
