 When compiled without garbage collection, mcs, mint and mono work as
 expected.

+on FreeBSD libgc sends itself a SIG_USR1 to stop threads prior to 
+collect garbage.
+so mono should not intercept it on FreeBSD.
+
+libgc/include/private/gcconfig.h:
+#   ifdef FREEBSD
+...
+#       define SIG_SUSPEND SIGUSR1
+
+I've tried to comment out this line:
+mini.c:
+add_signal_handler (mono_thread_get_abort_signal (), 
+sigusr1_signal_handler);
+
+and it helps _this_ problem.
+
+my project still has other problems running under mono@FreeBSD, will 
+report them separately after proper debugging.
