Re: master 2c79a8f 2/2: Use posix_spawn if possible.

[Saulius Menkevicius]

I believe this is not a problem related to C#/dotnet but generally with 
how signals are blocked on child processes launched with posix_spawn in 
the current implementation.

I will try to provide a minimal replication code that does not have 
anything to do with dotnet/C#.
