I think that we need some definition of terminology to avoid
confusion.  You mean signal protection, with the word "lock", not a
mutex, don't you?

My interpretation:
As malloc is not asynchronous safe, we need to protect calls to it
with signal mask.

IIRC, in Guile implementation, we don't call malloc from interrupt
context, I think we don't have this issue.
