sha1module_small_locks.diff patch is very similar to the changes made 
in #4751, except:
 - SHA1_GIL_MINSIZE is 8192 whereas HASHLIB_GIL_MINSIZE is 2048
 - There is no test for PyThread_allocate_lock() failure

Instead of copy/paste code in hashlib, sha1, sha256 and sha512 (4 
modules), can't we share some constants, functions or macros? 
 - the GIL minimum size constant
 - the long MY_GET_BUFFER_VIEW_OR_ERROUT macro (which can be a 

And about sha, why using 3 files for sha? Are the source code so 
different? In the GNU libc, they use "template" files (it's possible 
even with the C language using the preprocessor!): strtof(), strtod() 
and strtold() share 99% of the source code. Interesting content of 
strtof.c :
#define	FLOAT		float
#define	FLT		FLT
#define STRTOF		wcstof
#define STRTOF_L	__wcstof_l
# define STRTOF		strtof
# define STRTOF_L	__strtof_l

#include "strtod.c"

Refactoring to share code between hash modules will ease the changes, 
eg. release the GIL ;-)
