class OuttaHere(Exception): pass

then in your function
        raise Outtahere
when you want out, and in its callpoint:

try:
    map(myfunction, somehumongoushugelist)
except OuttaHere:
    pass

That depends.  If you need the write to md5s to complete, and it's
taking a long time, then you cannot of course quit this thread at
all (if you COULD kill it, the file wouldn't be complete).  If it's
OK for the file to NOT be complete, change the single write call to,
e.g.:

base = 0
stride = 8192
while base < len(result_str_md5):
    nd5s.write(result_str_md5[base:base+stride])
    base += stride
    if mustExitNowAtAllCosts():
        "close and erase the file or whatever, then"
        break
