### Describe the bug
When calling file.write (upload file to tencent cos by s3 scheme), there is
a very slight chance that it hangs or does not return.
`strace -p <pid>` output:
```
futex(0x7ff1bc73fe54, FUTEX_WAIT_BITSET_PRIVATE, 0, {tv_sec=72667171,
tv_nsec=27695447}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)
futex(0x7ff1bc73fe58, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7ff1bc73fe54, FUTEX_WAIT_BITSET_PRIVATE, 0, {tv_sec=72667171,
tv_nsec=32828162}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)
futex(0x7ff1bc73fe58, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7ff1bc73fe54, FUTEX_WAIT_BITSET_PRIVATE, 0, {tv_sec=72667171,
tv_nsec=37962838}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)
futex(0x7ff1bc73fe58, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7ff1bc73fe54, FUTEX_WAIT_BITSET_PRIVATE, 0, {tv_sec=72667171,
tv_nsec=43111763}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)
futex(0x7ff1bc73fe58, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7ff1bc73fe54, FUTEX_WAIT_BITSET_PRIVATE, 0, {tv_sec=72667171,
tv_nsec=48237693}, FUTEX_BITSET_MATCH_ANY) = -1 ETIMEDOUT (Connection timed out)
......
futex(0x7ff1bc73fe58, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource
temporarily unavailable)
....
```
maybe file.write had not release GIL, all python's threads is hang.
