+I would rather have some way of testing for this than mkaing the
|
|
+change on every distribution.
|
|
+
|
|
+This patch only turns the problem into a potentially different problem.
|
|
+
|
|
+What we probably need to have is a way of "probing" if these signals
|
|
+are being used, something like this:
|
|
+
|
|
+handler = -1;
|
|
+for (int i = SIGRTMIN; i < SIGRTMAX; i++){
|
|
+ sigaction (i, NULL, &old);
|
|
+ if (old.sa_handler == NOT_SET){
|
|
+ handler = i; break;
|
|
+ }
|
|
+}
|
|
+
|
|
+Now, the above only works if signals have been preset before Mono has
|
|
+been invoked. Am not sure if there is a reliable way of coping with
|
|
+this problem
