Timeout not working in ProcessPoolExecutor map function - concurrency

Question

I am trying to implement a timeout in my ProccessPoolExecutor but it seems that when I run the code, the timeout just doesn't work and the process continues as if the timeout didn't exist in the first place.
Here is the code:
from concurrent.futures import ProcessPoolExecutor
import angr
from angr.analyses import (
CFGFast,
Decompiler
)
from claripy import *
import os
#import ipdb
#ipdb.set_trace()
def decompile(filename):
p = angr.Project('/Path/' + filename, auto_load_libs=False, load_debug_info=True)
cfg = p.analyses[CFGFast].prep()(data_references=True, normalize=True)
for f in cfg.functions.values():
#print(f.name + " " + filename)
name = filename + " " + f.name
filepath = os.path.join('/path/'+ name)
try:
dec = p.analyses[Decompiler].prep()(f, cfg=cfg.model)
with open(filepath, "w") as f:
f.write(dec.codegen.text)
except AttributeError:
with open('/path', "a") as a:
a.write(name + "\n")
except ValueError:
with open('/path', "a") as a:
a.write(name + "\n")
except ClaripyOperationError:
with open('/path', "a") as a:
a.write(name + "\n")
except TypeError:
with open('/path', "a") as a:
a.write(name + "\n")
if __name__ == '__main__':
with ProcessPoolExecutor(4) as executor:
for result in executor.map(decompile, os.listdir('/path'), timeout=5):
print(result)
I think there must be some problem in the for loop as the result variable doesn't print. I would appreciate any help. Thanks!
