[Mono-devel-list] syscall vs. sigaction

[Dietmar Maurer]

The problem is that the libpthread overwrites sigaction, and does not
allow us to catch certain signals. So we need to use syscall directly to
catch the signal. Unfortunately this is very system/version dependent.

Maybe you can take a look on the implementation of libpthread on your 
system to see if it is possible to catch SIGUSR1/SIGRTMIN? What system
do you talk about? Does it have SIGRTMIN?
