That works like a charm.=20 >=20 > mlockall() mostly works now. There is still a, issue in wiring the stacks= of multithreaded program when the program uses default stack allocation sc= heme. Thread library allocates stack for each thread by calling mmap() and = sending address and size to be mapped. The kernel adjusts the start address= to sgrowsz in vm_map_stack() and maps at the adjusted address. But the su= bsequent wiring is done using the original address, which fails.=20 >=20 Can you, please provide stand-alone example which demostrates the issue ? I suspect this should have not changed in HEAD. --K4VW92aLFVAHIWRe Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iEYEARECAAYFAk+H370ACgkQC3+MBN1Mb4jX8wCgzQEv8IldTpqfJaFpT7auRRk5 huAAoKAENgJTjn9PtzjPKo1Hn5JNn5kE =hAfz -----END PGP SIGNATURE----- --K4VW92aLFVAHIWRe--
