working directory. The algorithm for this generally involves odd searching of
./.. paths. EG on a Sun, a trace of /bin/pwd gives:
open ("/usr/lib/ld.so", 0, 04000000021) = 3
open ("/dev/zero", 0, 07) = 4
open ("/etc/ld.so.cache", 0, 0) = 3
open ("/usr/openwin/lib", 0, 01010525) = 3
open ("/usr/lib/libc.so.1.8", 0, 022230) = 3
open ("/usr/lib/libdl.so.1.0", 0, 022250) = 3
open ("./../", 0, 035736104630) = 3
open ("./../../", 0, 0) = 3
open ("./../../../", 0, 0) = 3
open ("./../../../../", 0, 0) = 3
open ("/etc/mtab", 0, 0666) = 4
It is the O/S implementation of getcwd() that is the cause, your trace shows that
it may be over doing things though.
