Thanks for your answer.

Do you know maybe where it is documented that malloc is thread-safe,
then (on Linux/glibc)? I have heard a claim that if it is not 
documented in glibc's manual that a function is thread-safe, then it 
is not thread-safe, and it is not written there that malloc is 
thread-safe (though actually no other function either is documented 
to be thread-safe), and C standard doesn't demand that standard library
should be thread-safe.
