Ah ...
I've just (re)read the 9p(2) man page ... it seems clear now.
Thank you very much, cinap :-)

Hi, all
In a user space file server (9p(2)/9pfile(2)/...) I postpone the Rread
response if there are no available data,
in order to implement a suspensive read().
The client is (really?) suspended until Tread, but the read() sys call
cannot be interrupted by alarm().
It seems to me that the alarm note is received after Tread, as if the
process were totally freezed
waiting for the 9P transaction.
Could anyone kindly explain to me if this is correct and where is my
mistake ?
Thanks in advance
adriano
