Unfortunately not. The fork() is part of the elaboration of an Ada
package (using GNAT on Linux) ; since I cannot guarantee that no user
package will be elaborated before mine, I cannot guarantee that no
tasks (mapped on pthreads) will be created.
Anyway, I've found another way to solve my original problem without
using forking() at the program level but using the shell's
backgrounder.
Thanks a lot for your help however ! At least it helped us to point
out the original design flaw in our code (according to Solaris 2.5
documentation, fork() duplicates all the threads. Seems to be
non-posix from your comments).
