I've built squid with the -pg flag and run it in the no-daemon mode
(-N flag), without the initial fork().
I send it the SIGTERM signal which is caught by the signal handler, to
flag graceful exit from main().
I expect to see meaningful squid.gmon, but 'gprof squid squid.gmon'
only shows the initial configuration functions:
                                  called/total       parents
index  %time    self descendents  called+self    name           index
                                  called/total       children

There are 7 fork()s for unlinkd/diskd helpers.  Can these fork()s
affect profiling info?
