Description

_From [derek.br...@gmail.com](https://code.google.com/u/117968039472581148324/) on August 07, 2009 09:58:18_

the pending signal set and signal mask are supposed to be preserved across
an execve but for DR they are reset. signals set to SIG_IGN are also left
that way, but all other handler state is reset (should look that up)?
