gpgme: two separated contexts

[Björn Mayer]

Hi folks,

I just can't find out how I can create two separated contexts out of one  
GPG engine with the help of gpgme, so that I can import keys and delete  
keys in one context without affecting the other one!? Is this actually  
possible or is there always only one context for one GPG engine? If it is  
possible, how can I reaccess those contexts after having them closed?

I'm really thankfull about every single hint!!
Best regards,
  Bjorn
