>Description:
If a dummy function call is attempted while the inferior process is asleep in a blocking system call, the call fails.

The inferior must first abort the system call before attempting the dummy function call.

Attached is a patch that adds the procfs function to interrupt any system call in progress. When a dummy call is attempted, any in-progress system call is aborted before the dummy call is attempted.
>How-To-Repeat:
Test gdb.base/interrupt.exp fails
