From the the glibc manual (24.7.3 Process Signal Mask):

the previous signal mask in order to restore it later.  (Since the
signal mask is inherited over `fork' and `exec' calls, you can't
predict what its contents are when your program starts running.)

Thus I think it is a bug in Mono. Anyway, for convenience I will fix it.

Okay, fixed in SVN 4958.

I also fixed a problem with leaked file descriptors when using

gpg-agent --daemon some_command

Now all file descriptors except the standard ones and those already open at
startup are properly closed before the exec.
