The following rtsan tests fail with glibc 2.40:
```
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-Test/RtsanFileTest/OpenDiesWhenRealtime
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-Test/RtsanFileTest/OpenatDiesWhenRealtime
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-Test/RtsanOpenedFileTest/PreadDiesWhenRealtime
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-Test/RtsanOpenedFileTest/ReadDiesWhenRealtime
```
If I apply #108057, the additional tests also fail:
```
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-FileOffset64-Test/RtsanFileTest/OpenDiesWhenRealtime
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-FileOffset64-Test/RtsanFileTest/OpenatDiesWhenRealtime
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-FileOffset64-Test/RtsanOpenedFileTest/PreadDiesWhenRealtime
RealtimeSanitizer-Unit :: ./Rtsan-x86_64-FileOffset64-Test/RtsanOpenedFileTest/ReadDiesWhenRealtime
```
All failures follow the same pattern:
```
FAIL: RealtimeSanitizer-Unit :: ./Rtsan-x86_64-Test/12/19 (3380 of 7243)
