is writing to nohup blocking the process?

view story

http://unix.stackexchange.com – If I have a process writing to nohup and the storage where it writes to is slow, does it block the process which is running in nohup? For example: process A is running in nohup, it needs to write 10 lines to console it takes 2 minutes for disk storage to write these 10 lines into nohup.out (it write 6 lines and then it stuck for a minute waiting for disk) is the process A blocked until the remaining lines can be written, or not?
