  * type:  bug => merge

Comment:

 Fixed.  Three patches are required, first ghc:

 {{{
 Thu Feb 19 03:34:18 PST 2009  Simon Marlow <marlowsd at gmail.com>
   * Export blockUserSignals and unblockUserSignals (needed for #2870)
 }}}

 secondly for libraries/process:

 {{{
 Thu Feb 19 04:32:35 PST 2009  Simon Marlow <marlowsd at gmail.com>
   * Fix #2870: User signals are not blocked before 'fork' in
 runInteractiveProcess
 }}}

 and finally, for libraries/base, this isn't strictly necessary but I think
 it's prudent:

 {{{
 Thu Feb 19 03:42:17 PST 2009  Simon Marlow <marlowsd at gmail.com>
   * Set the IO manager pipe descriptors to FD_CLOEXEC
 }}}
