Ignore SIGURG on Darwin too This extends #2929 to Darwin as well as Linux. Running the example in https://github.com/golang/go/issues/37942 I see lots of: ``` dave@m1 sigurg % uname -ms Darwin arm64 dave@m1 sigurg % go run main.go received urgent I/O condition: 2021-05-21 16:03:03.482211 +0100 BST m=+0.014553751 received urgent I/O condition: 2021-05-21 16:03:03.507171 +0100 BST m=+0.039514459 ``` Signed-off-by: David Scott <dave@recoil.org> 2021-05-21 11:17:57 -04:00
Ignore SIGURG on Linux. In go1.14+, SIGURG is used by the runtime to handle preemtable system calls. In practice this signal caught frequently.
