under gdb: received signal SIG34, Real-time event 34.; received signal SIG35, Real-time event 35

[mw via Digitalmars-d-learn]

Hi,

I have this in ~/.gdbinit already:
```
handle SIGUSR1 SIGUSR2 nostop
handle SIGUSR1 noprint
handle SIGUSR2 noprint
```

Today I encountered:

received signal SIG34, Real-time event 34.

then I added to ~/.gdbinit

```
handle SIG34 nostop noprint pass noignore
```

Next, I got:

received signal SIG35, Real-time event 35.


I'm wondering why? and how many more such SIG<xx> I should put 
into ~/.gdbinit?

BTW, I'm using LDC2 1.34.0

Thanks.
