possible lightspeed sapi bug

[accassar]

When stracing PHP - I noticed:

unlink("2;/phpsessions/session_mm_litespeed0.sem") = -1 ENOENT (No such file or directory)
open("2;/phpsessions/session_mm_litespeed0.sem", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 ENOENT (No such file or directory)
unlink("2;/phpsessions/session_mm_litespeed0.sem") = -1 ENOENT (No such file or directory)

We use the multi level feature of file based sessions which it appears that the litespeed SAPI can't handle.
