Ok, that would throw some OOM exception instead so I wouldn't 
need to bother with it, is there something else in the GC that 
would override it during class instance allocation? I am finding 
it weird that ErrnoException doesn't let you specify the errno 
value explicitly, you usually check it in your code anyway (e.g. 
for EINTR and repeat the operation and not throw this error).
