os.chdir() and import

Under Windows and Python 2.1, I am sometimes able to use an
os.chdir('xxx') and then follow this with an import command
for a module located in the 'xxx' directory.
However, it seems that when the module doing the
os.chdir('xxx') and import-ing is executing because of an
execfile() command, this technique doesn't work and an
import error occurs.
A search of the documentation seems to indicate that the
import search path is determined only by the value of
sys.path ("...It [import] generally involves searching for a
``built-in'' module with the given name and then searching a
list of locations given as sys.path." -- Python Reference
Manual 6.11). I think "generally" here may refer to the
unique processing used for packages, but...?
Can someone clear this up for me? Should sys.path always be
modified instead of using os.chdir?
