Also, stop using syscall.PathMax that is not defined on Darwin

We could have gotten the signal before the handler was ready,

10884603d8 benchmark.bash: double write length 
Writing 1000 128KB blocks takes only 1 second and yielded
inconsistent results. With 2000, things look saner.

0f8d3318a3 main, fusefrontend: add "-noprealloc" option 
Preallocation is very slow on hdds that run btrfs. Give the
user the option to disable it. This greatly speeds up small file
operations but reduces the robustness against out-of-space errors.

Also add the option to the man page.

024511d9c7 fusefrontend: coalesce 4kB writes 
This improves performance on hdds running ext4, and improves
streaming write performance on hdds running btrfs. Tar extract
slows down on btrfs for some reason.
